Re: Need help with mystery compression readings

Yes it does, doesn't it? That was my first thought. No water in the exhaust, oil was clean, and cooling system pressure was good. It just feels, like a timing issue. It bothers me that the crank gets into a bind about every quarter spin by hand. Its possible I guess, the chain is binding on a sprocket although they look okay, the best I can see with chain on. Going to replace them and check compression again. I just learned about interference engines, and now I'm really nervous!! lol
Thinking back, I remember some pre ignition ping during hot weather last season. At this point, pulling heads for top end service seems a good idea anyway and I'll see more of whats going on, maybe.
