Re: Finding TDC (sorry, a bit off topic)

i am not sure about your car.. but with mine, i can remove the plug and 
insert something into the chamber till it hits the top of the piston.. 
rotate the crank until you feel the uppermost part of the travel...  vavles 
can open at differing times depending on the cam....

also if you can access the piston top directly... try using a dial gague to 
measure TDC....


regards

Ben
