[QUOTE="jeepjoe43, post: 429921, member: 19255"] You're results are probably correct and I'm with [USER=19498]@Gilaguy23[/USER] it's most likely a valve issue. You're not going to know for sure unless you do a tear-down. I'm actually surprised the numbers are as high as they are on the other cylinders. Years ago I had an 11:1 compression 4 banger that ran about 185 psi. Maybe these newer motors run higher compression, if nothing else this is interesting... [/QUOTE]
