Very cool friend ! Which gearbox was it ?

I still contemplate doing the Rev 1.8 or the flipped gearbox. Each one with it's advantages and disadvantages. :(

Looking fwd to hearing of your progress.

For the 'teeth on the water pump' to belt issue....

I thought about perhaps casting a TPU tread that would slide over the teeth itself and provide a smooth surface for the belt to grip. I forget if I posted this idea yet or not.

You could either cast in a mold the cover itself and then just place it over any existing water pump pulley or perhaps try and cast the TPU around the water pump pulley itself. I don't know if the pully is removable form the water pump easily or not.

Curious what you think are the disadvantages of the reversed 1.8?

I'm asking because I've run mine heavily for two years, including several multi-day road trips and some daily-driver use, without a lick of trouble related to the reversed rotation. Failed diverter valve earlier this year, failed clutch master, and a coil failure when I first got it on the road, but those can & do happen with any 1.8T engine, reversed or not, swapped or not.

Ya, I should clarify. Not an issue with the rev 1.8, a me issue.

I didnt want to get into tearing engine apart to notch the pistons, etc.

However, the info laid out makes it almost fool proof on guessing. Do I need to remove the head to complete re timing the cams?

Oh, and building the deck riser for the rear seat and engine deck.

I've almost convinced myself to reverse this motor. Lol.

Not trying to convince anyone one way or the other, but for me, just knowing that I'd never have to worry about the vanagon trans, and the high cost involved in lots of vanagon transmission problems, was by itself enough reason to go with the reversed 1.8t.

Just my biased opinion.

I'm just waiting for someone to blaze the trail on a reversed TDI drivetrain.

Shouldn't need to remove the head to re-time the cams. That said, I did find it necessary to remove the cams to remove the head, but that may be due to the way my head bolt tools are built. And seriously, re-timing the cams was the biggest head-scratcher of the whole build for me. Pistons mods wouldn't have been a big deal even if I'd had to do them with a Dremel instead of taking them to my buddy's Bridgeport mill.

Easy solution to the deck riser for the engine lid & seat -- get a Bay-window Bus and put the 1.8T in that instead. :lol:

If only I kept my 79 Bay Westy :) ...

I have 2 complete AEBs in my garage at the moment. The first is undergoing a 50Deg mounting with a FAS cradle and some TiiCo bits, intake manifold mod, etc.

Taking forever to get this one off the ground though. Maybe the second motor will be the upright Rev with my DVX Passat Tranny ... hmmm .... I never bought the flipped tranny adapter or parts yet.

I'd probably need to either remove heads or remove the crank to yank the pistons out for notching and skirt clearancing.

Since a reversed drivetrain requires an all new mounting setup, you can just lower the whole assembly so that it clears the lid. If you're not comfortable with the ground clearance, then raise the suspension to compensate.

There's no real way to get the pistons in/out from the crank side because the main bearing webs are in the way:

Pull the head; it's 10 bolts and lets you freshen up the head gasket. AEB head bolts are cheap, ~$15/set for Victor Reinz through ECS Tuning, head gaskets are ~$35 from the same place for Victor and Elring. I didn't find it necessary to take the manifolds or turbo off my head for the CCW conversion -- on the one hand they made it a bit more awkward, on the other they gave me plenty of potential hand-holding locations.

Good info, thanks Tristessa !

In my older age I think I'm getting less adventurous :) Air cooled, it would have been done by now but I haven't done much water cooled stuff. Doing the TiiCo was the most intrusive I'd gotten.

I'm looking to make a Vanabarrow now out of my wreck I'm trying to give away to assist in the mock up mounting that Zeit mentioned. My poor garage.... and wife, lol.

I had a laugh when Andrew mentioned he had an engine piece on the kitchen counter. One agreement my wife and I had after we moved into my first house was no car parts in the house.

Beter news- it turn out to be AGU with 06A block, still dont know the gearbox code. (havent seen it myself yet)

Other than occasionally bringing stuff to my "office" area of the laundry room to use the computer for parts lookup, I only bring things in the house when my wife won't be home for several hours ... and I make sure to hide or destroy all the evidence when I'm done. :lol: Parts that were shipped to me don't count as long as they stay in the box

My new house has a 12V only electrical system, car parts are welcome in the house and are even integrated into the house. I have a car stereo in my living room wall and a few cigarette lighter outlets throughout the house. The back-up to the solar power generator is a 2015 VW Jetta engine.

Thats awesome.

But how did you interface CANBUS with your dishwasher? lol. Just kidding.

I'm enjoying this thread. I'll be curious to see if poster running an (8v ??) CCW ends up with a long term working engine.

I'll try and take a better pic and post it in the near future.
(Note: this picture has funky lighting making the frame look like raw steel. It is, in fact, nicely painter gray and fabricated perfectly.)

NOTE- I put a new post on the front page of this thread mentioning the seals that should be replaced.

Gearbox code: DHW

Andrey- I'm a bit scared.

I have a gearbox from longitudinal 1.8T
and engine from transverse. ( present is present thou)

I might have any problems with flywheel/cluch and starter motor?

Thu Feb 20, 2020 12:26 am

I'm also woundering:

If I can leave conrod on piston and just rotate it (but piston backwards)?
I assume there are no diference on conrod position (one side or another- until one is attached to crank and other side to piston.

Might still change pistons- but this came up in my mind.
