I just picked up a 1987 ranger 2.9, its missing a few things so i decided to do a compression test before i fixed it up. my results were 120 on 3 cylinders, 115 on one cylinder and 110 on two cylinders. I was wondering if these numbers are ok. I know the general rule is no more than 10% difference between max and min but i can't find anything specific that says what the compression numbers should be on a 2.9. so do these numbers seem good?
