Those numbers are just okay. 155 is 91% of 170, but you might be looking at a slightly burnt/warped valve or a small leak in the headgasket that won't show you a real difference on a compression test. When you burn the ground strap of a spark plug, you've gotten the cylinder very hot, hot enough to warp the head, burn a valve or melt a piston.are those numbers good?
Yes I do. A 20 year old 7.8:1 CR engine with 200k on it shouldn't show that high on a compression test. I imagine he might even have installed some 2G or 8.8:1 pistons.do you think he was telling the truth
