    Valve Cover Gasket Change - Step By Step

    Step 1: Buy a rope Step 2: Hang yourself Actually, just pull the engine out. It might be easier. The inner cover bolts could only be accessed with an allen wrench. 1/4 turns at a time all the way out. Then the timing chain pulled the new gasket off when I tried to install the cover over...

    Hello all, 1st post. I have looked over the entire site and actually found a great write up on doing a valve adjustment.. The problem is, is that it mentions nowhere what diameter shims to use. Does anyone have this info?

    Valve shim strategy

    If a measurement is right at the edge of a range what is the best policy? Better to be on the loose end of the range for exhaust and tight for intake or other way around?
