IDI Engine / Franken Build, Need Parts Help 1y and 1.6TD Mixup
« Last post by vwpieces on May 13, 2026, 02:18:05 am »I have been running 1.6L TD's in a MK1 for 20+ years and know those pretty well. Also have Spare Parts.
A few months ago a 1Y short block came my way. Nice condition too. I want to use "what I have" if at all possible.
How much Taller is the 1Y compared to the 1.6TD? and am I correct in thinking the height difference is all above the IP mounting bracket holes on block?
Only 1.6 hydraulic head in the hoard is not great to say the least. It is flat but the usual cracks between seats. And there are hairline cracks in the prechambers. And the cam has pits starting on 4 lobes. Exhaust valves are Real Hard to find in USA, But I dug deep and found Int and Exh valves. Did New guides and cut the seats, I already had a new set of the INA 034****** lifters... just need a cam. Finding an 068109101L cam in USA, good used or New has eluded me. I have taken some basic measurements, comparing an 068109101W solid to the L and other than slight ramp difference, W is very slightly flatter as it approaches the lobe tip. I ALSO see PartsPlaceInc selling One cam for solid and Hydraulic heads... The cheepAss in me wants to just put the W in the Hyd Head.
As for a cam, I did see Cascade German has a cam they say will work on a 1.6L It is the 028109101F, 028109101C, 028109101G, Stock Eurospec camshaft for all VW TD AAZ and TDI 1Z/AHU engine codes.
Note: On AAZ's you will need 1Z/AHU valves and spring.
Fits the following:
1996-1998 Jetta, Passat, Golf TDI
1993-1996 Jetta, Passat, Golf TD (AAZ)
Also fits 1.6L TD - read on TDIclub and VWdieselparts on how these work in 1.6L engines! You would want to get our hydraulic lifters to go with it too!
As quoted from the ebay listing.
So is this a drop in cam for the 1.6 hydraulic head? I searched all those part numbers on this site and nothing 1.6 head related.
Or should I just give up on a Cam for the 1.6 and buy a complete Chinese AAZ Head off eBay for $260 to $320
Other parts I have and would want to use if possible
1.6TD pump with LDA
Have a spare set of 1.6 TD 155bar injectors I have new nozzles in and pop tested.
I think the 1.6 TD injector hard lines are a possibility? or AAZ?
Conti timing belt 028109119P
068 head bolts and timing belt tensioner I already have and I think are correct to use.
Piston protrusion is 0.9144mm and I believe that is 2 Notch, 028103383BKJ, ELRING 914856
Using the 068 cam gear, pump gear OK? Crank timing gear is the one from the 1Y.
Pretty sure None of my timing belt covers will work and I have some MK1&2 types on hand.
I should be covered for clutch/flywheel in 200 or 210 if I want to go there.
Misc gaskets and seals I should have, but oil filter housing to block I might not have, with the offset top hole.
I know a couple guys from vortex will recognize me.
Thank you in advance.
