From what I understand is ALL the diesel engines were made and assembled in Germany but shipped to where ever the car was built....  My guess is that there were some left over 11mm engines floating around that got used on '82 models.. TO be honest, I've never found a 12mm '82 model in this neck of the woods..

i dont find 12mm cars over here till 83/4 cars..

everything else has 11mm engines. and they are the correct numbers matching engine too.
92 Jetta GLI - Black, 1.6D w/ GT2056V turbo..
86 GTI - 4 Door, Med Twilight Gray, Tow Machine..
86 Audi Coupe GT - Tornado Red, All Stock.. WRECKED.
89 Toyota 4Runner - Dark Grey Metallic, LIFTED!

Turbo: exhaust gasses go into the turbocharger and spin it, witchcraft happens and you go faster.

Just make sure there are no cracks in the motor either, look at where the head bolts to the motor on the passenger side of the motor, found that out the hard way ...

.....uh.....not exactly. I'm working on a 1.6 that has 'Germany' stamped on the outside. I know for a fact the motor has never been opened. However, on one of the main bearing caps, it clearly says 'Mexico.' I think it's likely the blocks were cast in germany and sent to Mexico or wherever for the final work.

That, and nearly all of the 11mm 1.6 Blocks I've seen here in the USA were cast in Brazil: and they're junk castings aside from (or in conjunction with) the fact that the bolt holes crack. The bores wear out faster than similar-mileage German castings.

Correction

From what I understand is ALL the diesel engines were made and assembled  made/assembled in Germany

But indeed not everything was cast in Germany.. And I should also add AFAIK it was just the earlier (mostly 11mm) engines..


 I've had about 50/50 Brazilian cast / German cast blocks..  Oddly enough I have one of the Brazilian blocks with no cracks in the deck around the bolt holes, the crack was in the bore..  :-\

Drained the oil today. There's no coolant in the oil, so I suspect it's either headgasket leakage, or it's leaking up a bolt and into the coolant. (then again, maybe the previous owner was an idiot and bought into the "oh just add a quart of oil into the coolant" school of thought)

So the next step will be to drain my coolant and just keep an eye on it for oil.

Oil pressure = 80+ psi

Coolant pressure = 15 psi

So, you'll almost always find oil in the coolant with a oil-to-coolant passage headgasket breach,  but rarely the other 'way round... 80 psi > 15 psi.   :)
