I am not sure what the manual says, but I was running on the high side at around 180 or so. Just some numbers for compairison purposes.

i wonder why ours would be different. I highly doubt all my cylinders would off by that much.

Yup, that's why "?" says within + or - 5 is perfect.

It will also depend on the amount of oil on the cylinder walls. 5% within each other is just fine. If you have lets say a 135,142,132,87.....you can see which one would be losing compression.

A little carbon buildup from a leaky belly pan gasket may have something to do with the higher comp #'s.
