[Vwdiesel] 1.6l 11mm vs 12mm heads

[gary]

I could be mistaken.

But I didn't know there was a small vs large oil return in the 1.6.

There is the 1.5 head with smallish oil return hole. The 1.6 11mm, then
1.6 12mm, all else the same..

VWDieselParts.com has a bushing that allows use of a 1.5 head on the
early (11mm) block.
