Thanks for the reference to Rennlist... I was thinking about re-checking the cam timing as well; though I also learnt from my last rebuild that to get the same # again, you need to clamp the chain (for the left side) just like when it was first installed. This is the part that can't be done easily with the engine in the car
As for 1.7mm vs others, I was just curious if anyone can describe the results of deviating from "optimal". I think I understand what should happen, but what about reality?
