[QUOTE="Tazza, post: 116615, member: 82"] Your best bet is to set the clearance to spec, then re-test the compression, then you know they should be the same, or close to it. If any are low, i'm afraid the head is coming off and possibly slapping new rings into it. If the head is already off, there is no reason changing the head gasket alone if there is a possible valve seat issue. The idea of putting air into the cylinders one at a time at TDC through the injector or glow plug hole will help identify if it's leaking past a valve into the inlet or exhaust manifold or into the crankcase, past the rings.
