and what it's all going into




Want to transfer them to my 81 caddy 1.6na, exactly what parts do I need off the turbo jetta to make it work? It's an 83 turbo diesel that has a bad head and the rings are garbage. Sat in a barn for 10 years or somethin like that.

***Main Question***  Hoping to test the turbo before purchase but need some definite specs to measure for. I know I should be looking for minimal play both end-play and axial play, but how much is good/bad?

Any end-end play is usually bad. Axial play of less than a mm is usually ok.

Libbybapa has a post with a pic of the play. Not sure where it is. Try the search function.

Thanks! I searched and searched for turbo end play etc, but never with Libbybapa's name to narrow the search, only took a couple clicks from there... as long as THIS is the one you were referencing http://www.vwdiesel.net/forum/index.php?topic=21899.0

Thanks again!

I bought the car, $350 (more than I wanted but hopefully worth it).

1983 2door Jetta Turbo Diesel. Been sitting in a barn for 8 years. Story goes they parked it because it was blowing coolant hoses off. According to some of my classmates who were "diagnosing" it in their Alternate Fuels class, the rings are bad and the head is cracked really bad (I've confirmed the head as it is currently off).
IP looks really clean on the outside,
Turbo is tight, sprayed it down with PB blast hoping to free it up a bit, we'll see if that helps.
Manifolds look good.

What is the "checklist" (if you will) of differences between the NA's and TD's?
Intake manifold
Exhaust manifold
Turbo
Oil feed and return lines
Injection Pump
Injectors
Hard lines?
Head?
Cam?
Block?
Pistons?
Rods?
Crank?
Pulleys?

I'm trying to decide if I should swap the turbo parts (manifolds, IP, lines, injectors) onto my current long block, OR, take my time and completely rebuild the turbo engine and THEN swap it all in as a whole. Either way, is there a post or list of engine parts that are different/the same from the NA's to TD's?

Pix to come very soon.

Do both. Put the turbo stuff on your current block, and run it. In the meantime, build the TD block.

Is there any major body damage? If not that shell is worth much more than $350.

To answer your last question:

- hard lines are different, specifically 1 and 2, I think 3 and 4 are the same but 1 and 2 have to be different, to clear the injection pump boost compensator thingy
-head, at least with all the stuff on it is different, I think, I don't believe the bare head is though
-factory turbo blocks had oil squirters for the pistons
-pistons are different
-iirc the lower rotating parts are the same as are the pulleys, but I'm not 100% sure

I would definitely use the whole turbo engine, rather than piece together a turbo conversion, I think you end up with a more reliable engine that way though plenty of people have stuck turbos on n/a cars.

Small cracks between the valves on these motors are not uncommon and if they are not very wide, aren't really a problem.

Make sure to have the head pressure tested, sometimes small cracks between the valves that look totally normal or are within "spec" can leak big time.

I am sure you could make some money or trade someone that mk1 coupe for a nice condition 1.6td....

don't cut up a coupe,,,

[Rabbit79]

Any chance you'll be parting out what you don't use on your caddy? Those seats look to be in pretty good shape and mine on the old Rabbit are falling apart, so I could use some newer ones (if they'd fit).

That Jetta....does it have the small bumper turns that would go into MK2. Like the ones in my MK2 in the which bumper do I have thread in the troubleshooting section.

[RabbitJockey]

man i think i'd rather put that jetta back together and keep looking for another engine for the truck, its a 2 door factory turbo diesels, i've only ever heard of one other one

[RabbitJockey]

oh man and its a factory non ac car with a shift light... you gotta put it back together that thing would be hot

[RabbitJockey]

i'm really sitting here freaking out to the thought u want to use the parts from a mk1 jetta coupe factory turbo diesels to make a caddy a turbo diesel, but then i again i hate caddys because they all rust away...  really you gotta fix up that coupe
