Hey southkogs, I can't recall what engine you have - not to be picky cuz 120psi is good, but if you have the GM 3.0l it should be around 135. I had a similar situation with incorrect compression with my boat when I got it, 120, 140, 180, 160. After valve adjustment I have 130 across the board. Just a thought - while you're in there....
