  • 45k miles on conversion 08/18
  • IC T-bolt clamps get loose, the nylon locnuts vibrate and loosen with pressure. Use metal lock washers and metal pressure nut and use red loctite.
  • Insulate Oil Feed Line near the Glow Plug relay. Avoid a fire!
  • Install a boat hand fuel priming bulb at fuel filter line to IP to help prime

Caution

Unless you follow this build to the tee using all the same hardware, your milage may vary; YMMV.

Always document what you DO even if you follow this!

Label all wires, take photos, or videos. When you remove stuff from the old engine, do the same. If you're diligent with that and follow this; you'll do fine.

This tutorial is based off of a 1z/AHU engine. Other engines, YMMV!

Why mTDI and not a normal TDI?

I get asked this often. There is NOTHING wrong with a normal electronic TDI setup. However, for what I wanted for Betsy (Westfalia) a normal electronic TDI seemed like more a liability for the following reasons:

  • I'm in the middle of BFE, how easy will getting a sensor be? How much access to a scangauge will I have? Do I want to tot my laptop everytime I go somewhere?
  • Not that I'm opposed to electronics; I did rewire Betsy after all! Running an eTDI looom, just didn't appeal to me. I wanted to keep it simple like the OE diesel setup, just more power/torque to do shit!
  • Overall simplicity

These can all be argued, but it's the direction I went.

So, what *IS* a mTDI? A mTDI is essentially a TDI engine (1z/AHU/AFN ideally if at 50 degrees) with a mechanical pump instead of an electrical pump. Think of it as an AAZ with all the TDI goodness.

My last comment about the mTDI Debate

Prerequisites

Coolant System - THIS allows the heart to beat and not overheat and die. It's ESSENTIAL to be in tip-top condition! Your diesel Vanagon's coolant system is HOW old? And you want to do WHAT type of conversion? Do this first if you haven't already!

Here is my YouTube playlist of videos to this page. There's not as many videos as I initially thought. I think videos can move a bit quick and allow a miss of detail. That and uploading a large video over mifi is a challenge ;)

Diesel Vanagon/T3/T25 Donor List

This is a list of items that you will need to source from an 82' or 83' USA diesel Vanagon or look over the pond at T3s

  • Diesel Vanagon oil-pan & oil filler tube
  • Diesel Vanagon Transmission Bell Housing to allow 50 degree mounting
  • Diesel Vanagon Transmission Flywheel & Clutch (to later identify the TDI TDC mark)
  • Diesel Vanagon engine mount brackets; mostly the passenger side mount bracket. You may decide to change the driver side mount for clearing a larger turbo than a K03 or K03 hybrid.

The Details (my collected research before below work)

There's a decent article on TheSamba about what parts you'll need

http://www.thesamba.com/vw/forum/viewtopic.php?t=410813&highlight=ahu+intake

What isn't needed from stock AHU Engine

If going mTDI the following are not required:

  • electrical harness
  • MAF sensor
  • MAP sensor
  • IAT sensor
  • Injector #3 needle lift sensor - although you could use for a tacho signal
  • Fuel temp sensor (inside IP)
  • N75 & N18 valve
  • Crank Speed Sensor; you just need to plug the hole up which the sensor without the wire does well at. However, that looks tacky and leaves a busted sensor. The other option is to buy a freeze plug. Although you could use for a tacho signal

Turbo & Boost Controller

Read this on how to hookup

This is one of the "variables" that varies for what you want. The most common turbos tend to be:

  • K14 ; fits trapezoid AAZ exhaust manifold - about 10psi without a boost controller . Max 18-20psi with a boost controller - This was my initial choice and turbo used for Betsy's initial conversion. I may go GT2052, as I put larger DLC764 nozzels on.
  • K03 & K03 Hybrid ; fit triangle AAZ exhaust manifold
  • GT2052; requires slight mod for the AAZ 3hole and an adaptor plate for the trapezoid 4 hole AAZ exhaust manifold
  • Holset HE 200; requires adaption

Injector nozzles

This is one of the "variables" that varies for what you want.

here is a good read on nozzle sizes.

I wanted to do PP520's but Kerma ran out and offered DLC764's for the same PP520 cost. I went that route, but it did bump my allowed fuel up. I’m looking to go to DLC1019 down the road.

Injection Pump

There's a few builders, I suggest finding one that you feel comfortable with who you get warm fuzzies from.

VWDiesel FAQ

Also posting on their FaceBook Group

Injection Pump Builders

Giles Also has a great reputiation and he makes IP's for a living.

PartsPlace Inc. ask for Larry

WestyVentures - Karl M. has a reputation of building mTDI pumps based off a 4BT Cummins VE Injection Pump

Many hobbyists also use a Land Rover 300TDI Injection Pump modded setup. William Roberts on the TDI FB groups is popular person to obtain a LR300TDI

Possible 4bt pumps that would need modding; 0460424049, 0460424078

The pump I obtained was from Westy Ventures. I really dig Karl's pump!

Air Filter

Donaldson

G065433

I went with the G065433 with the bracket p/n H0084412 or H008444

G070017

I bought and haven't tested (will Winter 2018) a G070017 housing with bracket H002070 which is a little larger. This may be the "best" fit. I won't know till then.

Engine Mounts

Research

One method I was looking at was using SAAB Hydraulic mounts as seen here

Frank Grunthaner SAAB Hydraulic mount setup

http://www.thesamba.com/vw/forum/viewtopic.php?t=403215&highlight=ahu - rsxr - Saab engine mounts

I then discovered Tony Sanchez (TSI Engineering) who makes Syncro and 2wd 83+ carrier bars.

Now, this got me thinking about what the differences between 82' and 83' style carrier bars.

The newer 83+ bars move the motor brackets that are welded on the carrier bars back towards the rear of the van. This was done to allow for longer transmissions in the later years.

However, no one makes 82' style new carrier bars. To me the newer style is ideal for the following reasons:

  • They are solid mounted at the end of the carriers and not rubber NLA (yet supposedly accesible) bushings
  • There is no need for a cross member across the oil-pan to help 'stablize' it.
  • Supposedly the newer bars help reduce vibration which for a diesel is high on my list.

I have a set of TSI Engineering bars, which I plan to remove the motor bracket mounts and move them in position as where they would be on the 82'

Clutch

SMF or DMF

These two are highly recommended:

LUK 17-050 - less vibration

Sachs VR6 Clutch Kit - slightly more torque

I am planning to go with the LUK 17-050

get flywheel bolts

Saab 900 intercooler - Pretty Common

Air to Air intercooler in D Pillar - The Samba

The SAAB works, mostly because it's one of the ONLY intercoolers small enough with the ports on the same side.

However, upon fitting it myself (others have done it fine), I am changing my direction.

Instead, I'm going with a Renault 5 GT Intercooler which is 8x8x[3-5"] depending on what you get which would fit perfectly. The ports are also on the same side.

Renault 5 GT vs SAAB C900

Here is a comparison with the SAAB and a fan on it.

You can see from the Renault is a thicker core than the SAAB

The Process

This is where I'm going to linking to my youtube videos regarding my steps of building up a new-long block AHU engine from Bora Parts.

Here is the new long-block and a used engine:

Long Block (BoraParts) build-up

I want to state up front, that I used blue thread locker on all bolts even ones by hand. I wanted to make sure nothing rattled out.

I also used lined worm gear hose clamps for all hoses.

Engine Cover Plate

The new-long block didn't come with an engine cover-plate. This was purchased for the engine and the corresponding mounting hardware.

Intake

NOTE:

If using an AAZ exhaust manifold which points the turbo up higher; for better drainage to the block--if you drain to the block.

Get a PD130, NOT a PD150. The PD150 points towards the rear of the van. This "makes" sense till you realize it interfers with the turbo using the AAZ exhaust manifold that moves it up higher. The PD130 that points towards the front of the van is more ideal with the AAZ exhaust manifold.

If you use the AHU exhaust manifold and drain into the oil sump NOT the block, then you'll likely have clearance room to use the PD150.

NOTES

If using the AAZ exhaust manifold you position the turbo higher; thus, allowing to drain to the block instead of the oil pan.

There are TWO types of AAZ exhaust manifolds that work for this.

The older trapezoid and the newer triangle, both will work; however, some notes regarding the two.

OLDER - Trapezoid - Four Hole Unit - This will mount a K14 turbo stock without modification P/N 068-129-591G

Per Libby: "The metal ring on the exhaust manifold gaskets can face either the head or the manifold and in fact, two *should* face the head and two should face the manifold. There is a horizontal line of symmetry through the exhaust manifold, but if you place a vertical line through the fastener holes, the ports are offset 4-5mm toward the center of the engine. In other words, the two ports on the pulley end of the head are offset toward the flywheel and the two at the flywheel end of the head are offset toward the pulleys. The exhaust gaskets need to be oriented so that the offset is the correct direction. Furthermore, if you look where the gasket surrounds the stud, there is a skinny side and there is a side that has more material. The skinny side should be oriented closer to the intake manifold."

Then a light smear of permatex copper on both sides of the exhaust manifold gaskets

Here is how the gaskets should look orientated before the permatex sealer

Vacuum Pump

I had made a video, but I lost it. This is a very simple process, so I will just explain it here.

If you look at the end of the vacuum pump you'll see it has a slot. Then when you look into the engine hole a receiver for that slot. The goal is to lube it up a little with diesel oil so it's not totally dry. Then go in the angle of the slot. I usually turn clock-wise till it falls seated. One way of knowing if it's seated or not is you won't be able to see the greenish/gray O-ring as shown in the photos below. Then just tighten up the bolt and bracket. In order to get the bolt to even up enough to screw into the hole for the bracket, you may have to wiggle the bracket a little.

Oil Filter Flange

NOTES
053115417A - Oil filter flange; This flange has been used for all the 1.8-1.9 gas and diesel engines (AAZ, 1Z and early AHU). The difference being the later AHU adaption have two 10mm ports and one 12mm port (for the Banjo Bolt N0210717) instead of the three 10mm ports that the gas/ABA engines use. There's no 'real' way to know which you get by searching for the P/N. Your best luck appears to be searching for a "MK3 TDI oil filter flange" or maybe "AHU" also in the search string.

There's also two other indicators of the proper one you received.

First the third port is larger than the first two. (photo coming soon of comparison)

The second visual indicator is a bit more positive you got the right one from what I have read on the forums and Parts Base.

Within the below photo in the red circle is 028115436 - choke; M12X1,5; AAZ,,AHU,1Z which is what you want for the diesel engines. From my research, and what I received the first time, gasser engines do not contain this.

Oil Pan

This section will include details on swapping the 1.6na DV oil-pan for a 50 degree install, as also the 4cyl windage tray for it. At the same time we'll be swapping in an 82' diesel oil-pump to get the desired plunge shaft length.

NOTE: You must leave the oil-pan loose and mate to the transmission first THEN once the transmission is mounted tighten up the oil-pan along the edge level to the block. In addition, there are TWO bolts near the flywheel that are hard to reach. You'll need to rotate the flywheel and use the elongated space to tighten those two bolts. Make sure to dab a little bit of loctite on those two bolts. You do NOT want them coming loose by accident.

DV Pan swap to AHU

Its as recommended to get longer oil-pan screws for the windage tray, but the stock 1.6na CS engine DV pan comes with the following 20 bolt size M6x22

Get M6X25 for clearing the windage tray @ 10Nm or 7ft/lbs. VW specs a good bolt for this p/n N10302402

These should be tightened to PROGRESS

Now for the actual windage tray itself. It was included with the AAZ and sometimes with the 1Z and AHU engines, but was more common in the gasser inline 4's. It was NOT part of the 1.6na engine.

That said, my 1Z came with a windage tray, but sometimes the sealant is so bad it fucks the seal up and you'll need to get a new one.

The Windage Tray P/N is: 037115220B

DV Oil Pump Swap

You need to use the DV oil-pump NOT the AHU oil-pump; unless you modify it by moving the DV pickup to the AHU oil pump.

Reference
  • Bentley 17-1 - 1Z / AHU specific
  • VW W42-011-294-103B p17-6

Once you have the oil-pan off the AHU you'll see the oil-pump. However, if you're long-block is like mine it may have a windage tray installed.

AHU Windage Tray Installed

Now you'll see the oil-pump as the silver device with the black tray delay off to the left. This is the oil pump you need to swap.

Here is the AHU (black pickup) oil-pump vs a new DV oil-pump (all metal)

AHU CS oil-pump-comparison.jpg

You'll see two bolts (black heads for me) where my fingers point. These will remove the oil-pump (13mm)

AHU oil pump removal.jpg

When installing the DV oil-pump the two pump bolts get torqued at 20Nm

NOTE: The AHU oil-pump bolts are LONGER than the DV oil-pump bolts. If you do not have the original DV Oil Pump bolts you need to get two of either of the following P/Ns: N01037510 or N0103753 with the spring-washers N0122265

Installing Oil Pump & Windage Tray

See the note above about final tightening that happens AFTER the transmission has been mated to the engine! When ready to tighten, use blue thread locker for the bolts. It helps keep everything snug.

I've seen two types of AHU windage trays. OEM and from Victor Reinz. The VR ones are slightly larger where they can with caution and care fit over the DV oil-pump. The OE ones do not.

I just suggest installing the pump first (the bolts will be 13mm tigten to 20Nm) and with blue thread tocker. At that point you can let the windage tray hold on the pump like this

ABF Serpentine Setup

This bracket and setup, WILL keep your alternator lower than the deck-lid; thus, the arm on the IP being the only possible interference. That interference though is negligent, as you just trim the foam for clearance of the throttle arm. However, if you need to cut-out the deckled here's a File:Andrew Libby Engine Lid Template.pdf template for you.

Since I don't have power-steering nor do I have air-conditioning, I can simplify my setup and make it more reliable with a serpentine setup rather than a v-belt system.

This can be accomplished via various methods as mentioned below. I went the ABF way

Reference

I ended up using a system from iABED Industries found on the VWVortex

He makes a custom bracket, that's really beautiful, but if you want to source / find your own VW specific parts read these threads:

Coolant Flanges

References:

Block to Pump Flange

I thought long and hard how to approach the mTDI coolant flange dilemma.

There's a few various options to accomplish this:

  • Use the 1.6na aluminum flange p/n 068-121-133M with an adaptor plate to position the adaptor similar to the AHU orientation. The photos I saw of this looked like it'd cause a possible other leak, looked hooky, and just bad in my eye.
  • Use the later AAZ sensor p/n 357-919-501

green ring) on the plastic AHU flange p/n 028-121-132A This solution is bad for two reasons to me. First it's plastic and in my mind more prone to cracks. Second now you've mix-matched the sensors on the engine.

  • Custom baby!

In the end I felt a custom solution was the cleanest and best solution. For the following reasons:

1.) The material will last the lifetime of the van similar to how the 1.6na flange would; however, using the 1.6na flange you have to modify the hose route which isn't too clean to me; more parts. Or you would have to create a modification plate which in the photos I saw looked kinda hooky more possible leaks.

2.) I could have went with the normal flange itself and blocked the over-flow barb (which over time may need replacement) and used a later AAZ temp sensor (for coolant temp & glow plug), but then you have a mix-match set of sensors on the van. This would make over-all support a bit more "specialized". The custom flange mimics the diesel setup to the T.

I already have a sensor at the front of the engine block for the glow-plug, so that'd just be 'blocked up' using an AHU flange which is dumb. The engineer in me says mixing sensors makes supporting more a chore.

Custom mTDI AHU diesel vanagon coolant flange from Legacy Mold & Tool talk to Charlie! (502) 348-8151

NOTE: The correct hose barb I have installed is a 3/4" NPT to 1" ID (the one pictured be low is a 3/4" ID which I found out was wrong)

NOTE: The bolts on the flange are M6x55 and torque at 7nM, just use blue threadlocker and tighten snug by hand

NOTE: What type of nozzles to use are more a personal preference of what you're give/take on the engine's performance you want to have.

Okay, it's likely you'll end up with a pair of used injectors, and you'll want to get them tested and put some new nozzles on them.

Very few place allow installation of customer supplied nozzles, so you usually buy the nozzles at the same place you do the calibration/mounting etc. I used KermaTDI

Once the injectors are in it's time to install the spacer & holder.

First the spacer goes in like this. You can see the bevel should face up as the way I am holding it

At this point you can install the banjo, banjo bolt, and banjo washer/oring for injector #3. The washer/o-ring goes towards the injector hence, in the orientation I have it held, it'd fall off the bolt.

TDC Process

So, now that you have everything on the engine sides, it's time to get serious about pulleys and belts.

This will walk through TDC of all but the flywheel. It's good practice for the n00b!

When you install the flywheel and TDC that, you'll want to make sure everything else is at TDC and then tighten the timing belt. It'll happen soon.

Ground Zero (TDC)

From a knowledgable person; Michael Courtenay on the Diesel Powered Vanagon FB group

"You can only verify TDC with the cam or injection pump after the engine is timed and the belt is on.

Obviously if you have no belt you cannot verify that #1 is at the top by anything other than the crank. Without a belt the cam and crank can move out of phase with one another, so you need a way to confirm each of them independent of one another, hence the plate, pin, and crank tool.

The Metalnerd crank pulley tool bolts to the face of the crank sprocket (with harmonic balancer removed, but with the crank bolt in place). The face of the sprocket has four M8 bolt holes. The holes are not in a perfect square, so the tool only bolts on one way, or 180 degrees out from that way. That would be with #1 at TDC or with #4 at TDC. Those two travel together on the crank though, and 2 & 3 travel together. In practice it doesn't matter which way it fits if the engine is not timed yet, because that then becomes #1 TDC.

Any marks on the dampener or flywheel are secondary and can be used to check crank position once the engine is in the vehicle. They are not necessary if you have the tool.

The tool does come with the Deluxe set. It is a round piece of metal with an ear bent perpendicular to it. If you hold it up to the crank sprocket it will be immediately obvious how it fits.

You can also check for TDC by dropping the oil pan and verifying that the piston is all the way up.

The notch on the rear of the camshaft is cut off-center so the locking plate will only fit into place when the #1 valves are in the correct position."

HOWEVER, you WILL want to recheck TDC after you mount the flywheel. This will though get you used to checking TDC on the Crank, IP, & CamShaft

NOTES:

  • When you turn CCW of TDC to get the plunger at the lowest point, it may take a quarter turn of the flywheel to get that. It may feel like a whole half turn. When it stops, that's when you want to zero it out.
  • Press the CCV tube down, it may press on the dial gauge and throw off your reading
  • Remove the injector lines FROM the injection pump and loosen the ones at the block. This will allow easier fitment of the injector lines after you turn the IP to adjust the timing.
Crank

You need to set the crank to TDC. This is accomplished by turning it till you can set the crank lock tool

Betsy's Route

I installed a LUK 17-050 DMF Clutch & Flywheel setup. I had to trim the bellhousing to get it to fit properly and able to spin. That's mentioned in the transmission section :)

Transmission

I'm starting with an 82' diesel, so I *have* to upgrade my transmission or expect to blow shit up early on.

I'd love to go 5spd, but not knowing enough to go this route, I have decided on a rebuilt DK (80-82 air-cooled Vanagon transmission).

Most converting to a TDI should swap out their stock DV transmission for something else.

Tranny Upgrade Notes

The TDI will not have any difficulty cruising at 3500rpms or even a bit higher. The only downsides are noise and a bit of a drop in fuel economy. If your preference is to cruise at 65, then gear 3,000 @ 65MPH. With that gearing you will be able to cruise at 70-75MPH if need be and will still be high enough in the rpms @ 65 to develop enough HP for cruising with a 'cushion'.

"Max torque on a stock TDI is around 2200 RPM. Max hp is around 3800 RPM. The TDI seems happiest in a Vanagon between 2600 and 2800 RPM. You are above the max torque, but well below the max hp. Your gearing and tires will dictate what speed that is." - Mark Ward - The Samba.

In this ratio, I would think a Westy would be more the range of 2700-2900rpm to account for the extra weight; ~700lbs last I heard!

Till a better place linkage differences here

Obtained a DK air-cooled transmission

Here are some good calculators:

Betsy's Decision

Since each setup is different for me I decided on the following:

It "is" possible to put a 5spd transmission in the 82' style setup, but you'll be having to play with linkage and the like. I've read of a few who have done it. It was a split down the middle if it was worth the trouble than just going the 4spd.

For this reason, MOST people who do an 82' diesel conversion just roll with a DK (80-82 air-cooled Vanagon) transmision with a taller 3rd & 4th gear. As it will fit with the diesel vanagon bell-housing attached to it.

If you're transfering your DV components for the conversion, KEEP your diesel bell housing bolts that go into the engine.

I went with the HD after reading about a Subaru H3 using it and others saying it's beefier than the OE from their visual inspection.

You'll also want parts

Lightly grease the bushing and teeth of the shaft when installed without the TOB it'll look like:

Betsy Clutch Cross Shaft.jpg

Now, we're ready to install the TOB. Use a light coast of grease inside the TOB where it slips over the shaft. Make sure to slide it over in this orientation and then use a flat head screw-driver to pry the springs around the hooks:

Marking new TDC on TDI Flywheel & Pressure Plate

To be able to get TDC set on the CrankShaft using the FlyWheel, the engine now needs to be removed off the stand and lowered.

Betsy AHU lowered to ground.jpg

This is where things get interesting.

I'm using the TDI input shaft, which means using a TDI clutch & flywheel. In my-case the LUK 17-050 DMF which has the flywheel/PressurePlate already attached.

In my setup there's going to be two hurdles:

  • Making clearance for the DMF flywheel with the diesel bell-housing
  • Getting the proper TDC mark on the TDI Flywheel.

First cover the input shaft and Clutch Cross Shaft with masking tape. Then do a light spray of white spray paint inside the bell-housing. A very light spray. Then let that dry.

The Diesel Vangon Flywheel & Pressure plate have what you need to do this. The Pressure Plate will have a V indicating where TDC should be set

DV FLYWHEEL TDC MARK.jpg

Now, I installed the DV pressure plate & flywheel to the AHU engine. Here's a photo of the flywheel installed (forgot to do one with the PP on it). Remember the PP showen above has the V which is what we want to get TDC of the Crank Shaft

DV Flywheel on AHU.jpg

Now, this is where I had a problem, and thanks to my friend Kim Mohr who gave a solution. When turning the crank to adjust to the DV TDC mark, I kept hitting a valve. I ended up having to lossen the camshaft studs and adjust it when doing the flywheel TDC mark. Then I tightend the studs back to torque spec from the Bentley. I then turned it a few times to make sure it cleared and had a few full rotations of the crank. I wish I had taken photos during this procedure, but it was a spur of the moment figuring with two others. So, a bit hectic.

You'll at this point when the crank turns freely you'll want to mount up the DMF flywheel to the engine. Then mount up the tranny with the Bell Housing to the engine.

Once that's mated, try turning the crank. You "should" have interference. Go Clockwise till it stops then go CCW till it stops. Do this a few times.

Now remove your transmission & bell-housing.

You should see where the paint was rubbed indicating where to trim with a grinder to let the flywheel clear

DV BH Paint scratch TDI flywheel.jpg

Trim and remount and make sure it rotates cleanly.

Then remove the transmission and the DMF clutch/flywheel and put the DV flywheel/PP back on the engine.

Now mate up the transmission again so you have the BH mark for the Flywheel/PP. Turn the crank till you have TDC of the flywheel, then install your crank-lock tool from MetalNerd.

At this point TDC the IP and CamShaft as indicated above.

Once, everything is at TDC; crank, camshaft, and IP

You can now remove the DV flywheel/pressure plate

At this point you should install the pilot bearing lightly greased tapped into the spot on the engine

Now, the BH will give a TDC mark of where the DV was that you now mark on your TDI DMF Flywheel/PP as indicated below;

Transmission Mount

This is the best time to install a T3 Transmission Mount (74mm)

There is NO easy way to remove the old bushing. I drilled holes, sawed, cut, etc. I eventually got the damn thing out. You'll want the end result like this:

Clutch Slave Cylinder

I replaced my Clutch Slave Cylinder while I was swapping the tranny out. I figured it was a smart move. It's P/N 251.721.263 and available at Van-Cafe

Removing the old slave-cylinder can be a real PITA. Removing the line from the cylinder even more so! Use a torch on the flar nut, let it cool spray penetrating oil, and repeat a few times tapping the flare-nut with a hammer. Eventually it'll come off OR do the flare-nut on the other end of the line.

Turbo Oil Feed Line (Turbo to Oil Filter)

I obtained my K14 turbo Feed Line to Oil Return from DarkSide Developments

darkside-braided-oil-feed-line-for-1-6-1-9-td - which is 12mm on both ends with a banjo

Turbo Oil Return Line to Block

Ideal drainage is 12pm in and 6pm out.

I'm using a 5/8" AN Push Lock hose barbs & hose. Check temperatures! I got Parker 836 rated to 302.

Use Quality (brass, steel) fittings over aluminum if possible. I had two aluminum snap with a little torque to tighten. Areoquip is a good brand overall.

When you don't use the AAZ exhaust manifold, you generally tap to the oil pan for the oil-return instead of going into the AHU block.

Since, we have an AAZ exhaust manifold, we're going to do it right into the block.

Reference
  • K14 oil drain to block port size/thread M16x1.5, but I have heard also M18x1.5. The block end is M18x1.5

On the K14 you'll only be able to get to 5:45pm on the clock and not 6pm, but it will be good enough to work.

Parts
  • M16x1.5 to AN 10 (the metric side should have a crush washer)
  • M18x1.5 to AN 10 (the metric side should have a crush washer)
  • AN 10 Female 45deg 5/8th Push Lock Hose Barb
  • AN 10 Female straight 5/8th Push Lock Hose Barb
  • AN 5/8th Push Lock Hose

This is a view from behind the line on the engine to see it's horizontal flow

Betsy-v1.0-oil-return.jpg

The below photo shows the spacers. It was still dirty when test fitting with loose. You have to clock the turbo so it clears the exhaust to install the spacers. When you get them tight position horizontal with the exhaust manifold it's near. When you reclock the turbo, if it some how backs out, it'll only do it about 1/8" a turn and hit the exhaust manifold. Kinda a slight fail-safe instead of it pouring out.

Harmonic Balancer & Lower Belt Guard

Everything about this is pretty straight forward except two things.

1.) The bolt for the left bottom is wrong in the ETKA. It should be the one listed below. It's slightly longer than the other M6

2.) The T bolt is a bit confusing, but it just goes through the hole on the WP and locks into place on the lower guard. You'll see by the photos.

Engine Carrier Bars & Brackets

Ah carrier bars. So, there's the 82' style which was an one-off in the USA and then 83+ which was when the engine got pushed back roughly 2" towards the rear to accomodate for a longer WBX transmission.

When you have an 82' diesel, it make sense to keep that arrangement. It's also been argued by some the 82' style allows easier access for working on the engine, as it's not 2" closer to the rear.

Upgraded 82' Bars

It's known that the 82' bars provide more vibration which some will argue. Myself when I researched the interwebz the general consensus was that they are not as good with vibrations compared to the newer 83' style carriers. Most people don't even notice a real difference. However, with my physical health, I will do whatever I can to make it more comfy.

Also, the cross-member that connects the two carriers that goes over the oil-pan is a very weak link. I have read where others have used a stonger tube bar to help it from twisting over. Because the 83' carriers don't have the rubber bushings on the ends there's no requirement for the cross member bar.

That said, I went with 83' style bars, but just not ANY 83' bars though, Tony @ TSI-Engeering found on TheSamba makes. He also makes a 50' degree DS mount to clear the turbo. I didn't realize that when I bought my DS mount.

I got a set of his 83' 2WD Carrier bars and then moved the motor brackets (had him lightly mark them where he installs) and then moved it towards the front of the van 2". It mounted perfectly!

I then installed his Isolator Mounts which use VW P/N 357199402BMY (Meyle has a better fitment with the isolator bracket I've read).

This allows for a more modern and easily found engine mount; searches will present it as a motor/transmission mount. It appears it was more widely used as a transmission mount.

Relocating Starter Battery

It became apparent in my setup, that the 82' diesel vanagon battery would need to be moved. I wasn't going to the front passenger, as I have a house battery ther. I also wasn't going to give up my retail under the bench seat.

Andrew Libby on the forums did this first, but his photo is very poor; however, the idea was to cut above the engine bay right of the transmission.

Photos

The initial mark for the hole. I have an Odyssey PC1200 which is smaller than most starter batteries. I don't plan on switching to a different type/brand anytime soon, so that's the measurement I made for my hole.

My floor had some serious sound deadening added and paint, so yours may look different.

DV Battery Relocation-a.jpg

Hole cut, but a note here. There's four spot-welds that need to be removed to remove the new 'lid'.

The cross member needs to be removed, as it's not structural for anything but helps hold the mat that's above the transmission. It will be in the way of the battery.

DV Battery Relocation-b.jpg

This is the "new" lid that I'm going to modify. Use some JBWeld to fill in the holes and you'll be good!

DV Battery Relocation-c.jpg

NOW to make a box for it!

Intake & Airbox

The reason for the starter battery relocation was for the Donaldson G065433 air-box with the bracket p/n H0084412 or H008444

I wanted to get the intake routing as direct as possible with my setup.

Using a passenger fabbed snorkel coming into thje passenger side, putting the Donaldson as shown below, makes it way easier and direct for the hoses.

NOTE: I had to remove the tabs off the old DV snorkel and those foam bits. It was then able to fit into the passenger side with some wiggling effort with the 3" hose. It WILL go, but be patient and take your time. For securing the hose to the snorkel use Rescue Tape!

Photos

Installed view without hoses, yes the clips are functional! The lower is a little bit tight, but it works!

Betsy Intake Box-a.jpg

This gives some idea of how much hose clearance I'll have. The taillight is installed in the last photo to get a reference:

Betsy Intake Box-b.jpg

Betsy Intake Box-c.jpg

This is the snorkel and 3" hose attached. It was a bit to work the 3" around the snorkel, but it WAS possible!

DV snorkel 3inch tubing.jpg

This is the snorkel wrapped with Rescue Tape to attach the hose. This is the BEST tape to use compared to "duct-tape". No substitution for this project!

DV snorkel rescued.jpg

This is how the snorkel will look when test-fitting. You'll need to remove the tabs/foam for it to fit

DV snorkel moved ps.jpg

Snorkel hose is now attached to the Donaldson as shown in this photo looking in from the rear light

Betsy Intake Snorkel Hose Routed.jpg

The red one is going to the turbo. It's a tight fit! But it's doable! It's 2.5" on the Donaldson side to 2.25" on the metal pipe

Betsy Intake Snorkel Hose Routed-red.jpg

Intercooler

The Renault 5 GT A2A IC is a good fitting IC for the Vanagon! It's roughly the same size as the SAAB C900, but a tad larger and a thicker core.

You DO have to modify the van a tad for fitment, but it's a small not noticiable change.

Modifying the van

Here is the lip that needs to be folded flat for the IC to fit

IC-cuttab.jpg

I marked where to tin-snip with a sharpie. I moved my line further so the two outer lines is where I snipped.

IC-test-fit-lines to benb.jpg

Here's the IC test fitted with the lip cut and bent outward; later you'll bend it back inward to hold the IC more to the other side of the wall.

IC Lip bentout.jpg

Another view of the lip

IC Lip bentout-b.jpg

Final Test Fit

Here is a sample fitment. You can go further back than the SAAB thus allowing more of the downward flow into the IC directly. There's still a 45degree roughly out the other side of the IC into the engine bay. Keeping the upper and lower pressure zones fluid.

Renault 5GT IC DV Placement.jpg

Here's one from the side

IC side fit-b.jpg

Mount & Shroud

Bent a chunk of steel and made a bolt hole. In the body of the van I made a 8mm X 1.25mm bolt tap.

Update: I tapped a second bolt hole verticle to stabilize the bracket

Renault5GT mounted in DV.jpg

There's not much a shroud required! You can put some weather stripping at the top of the area whre the IC mounts, that'll flush the upper area. Near the tail-light entrance, there was a small patch whre upper air could get to the lower area. I used alumnum reflective tape to cover that hole/patch. Very minimal needed for the shroud. The IC fits perfectly there!

Intake & IC Routing

Here are some photos of how I routed the Intake to the Intercooler

Here are some better detailed photos

NOTE: Instead of getting a 57mm (2.5") race-pipe like I did (delete EGR pipe) off the intake, I suggest get a standard 2" race pipe (50mm). After having done this, it would have been easier.

And closer to the tee off the turbo

Revisions

I kept getting popped hoses off the IC and the joins. I eventually settled on this setup which seems to be a LOT more solid.

Get two HPS HTSER90-200-225-BLUE and trim them down to fit as shown.

Coolant Tank

I wanted to replace the old diesel vanagon coolant tank with something more durable and suitable with the 1.9 engine.

I got the Rocky Mountain Westy (RMW) 1.9 WBX aluminum tank and bracket; they are separate.

Coolant Level Sensor

DO NOT CONNECT

This is properly hooked up, but WILL NOT work and will make your shit go crazy. Leave the sensor disconnected and use the standard DV setup. You can correct to a later circuit and use the sensor down the road if you wish.

The diesel vanagon to my knowledge in 82' didn't use the coolant sensor wire as shown below. I am NOT sure if the circut on the other end is intact or needs an update for this to work; future project.

DV Coolant Level Sensor.jpg

However, may as well hook it up to the new tank till you can verify if it works or not. That's half the setup!

The wires are like this. Brown is ground, and the other wire is for the level sensor

Hooking up to the new tank would be like this. The ground is connected to the right mounting bolt of the tank.

This is the relay not mounted against the firewall. I did this for the photo to allow a better view of it.

Also note, the two TDI glow-plug harness wires are male quick-disconnect ends. The old DV is a spade. What I'm doing is making a "Y" which goes to both TDI Glow-Plug harness wires with female quick disconnects spliced into the old DV glow-plug wire.

You "could" wire a second relay, since each wire on the TDI harness is for two glow-plugs. That way if you lost one relay you still have two glow-plugs functional. However, it's just as simple to buy a new relay and use the old as a spare relay which is what I did.

Start-up the Engine!

Once you've replentished the fluids; oil, trans, and coolant.

At this point, we can start the engine to see if everything worked right! Remember to make SURE you can crank over the engine manually via the crank-shaft and a 19mm socket! Do it four times to make sure you get TDC at the flywheel each time!

Bleed air out of the lines

Use a hand vacuum pump to attach to the Return line port (disconnect the banjo bolt) and suck air through the fuel line with the pump. I used Viton / Tygon hoses for the fuel line. You can get a clear on to see bubbles easy while clearing the air out.

Then crack open the lines half turn on the injectors. At that point cover with a paper towel or real towel to catch the diesel squirting. Now crank it over about 15sec wait 15sec, then crank again 15sec. Do this till you get only diesel bleeding from the injectors and not air. Once satisified tighten up the 17mm nut on the injectors. Then clean up any diesel that was squirted around.

Once satisified start her up!

- Betsy's first start!

Break-In Massaging

The first 500mi-1000mi will be what you'll find out for any minor tweaking needing for your setup.

In my case, the wastegate on the turbo was rubbing against my engine bracket on the driver side. I had to remove and trim it a few times to get it happy.

I also had my inter-cooler rattle on the body a little, where I used some weather stripping to soak up that vibration.

Also, had one injector line at the IP drip requiring a better bend of it to get it center with the line hole.

Little things will crop up like this after you start it up. So, don't go driving out of town ASAP.

Start her up, let her idle a bit, manually let it rev across various spectrums gradually.

The Little Things

This is where I added an extra dab of customization.

Oil Filler Tube

So, many like using the dipstick from an 83' style setup, and just filling via the oli-filler tube.

I wanted to keep the 82' DV Setup, since I prefer it.

I had the plastic tube made into aluminum (the rest are long gone) because that plastic tube breaks and is NLA.

If interested in a similar tube that utiilizes your existing oil-filler funnel & cap contact Steve @ Guyer Machine Shop and mention you'd be interested in the aluminum oil-filler tube made for William & Ralph. He'll know what you mean.
