Are 3sge beams motors interference motors?

Pull the valve cover and look at the valve clearance. If it it way too big, then that is all the "proof" you need.

Rough luck, hope it doesn't cost too much!

[QUOTE=mic*]I would concur, but there is no particular reason to think in this instance that a low compression reading would be to do with rings or lands. If its low, its gonna be a valve issue. QUOTE]

a leak down tester will tell you if the valves are leaking and whether inlet or exhaust side are doing it, not only ring/piston leakage, and it will tell you how much they are leaking
