[Vwdiesel] More Quantum questions?

It's a notch in mine, not a mark. Not sure why yours is just a mark, unless 
someone put one in there that didn't have any marks, then just painted one 
on there.

You can use a piece of wire in the #1 cylinder hole. Pull the injector, and 
put it in there. Then, just turn the engine over till the wire is pushed out 
the maximum. That's your TDC. You can also use #4 (if it's easier for you), 
as they are in time with each other, just 180 out. IOW, #1 and #4 go up and 
down together. And, #2 and #3 are also together. Once again, just 180 out 
from each other.

Once you get TDC, I'd definately find a way to make a permenant mark there.
