Whats good compression?
Im looking to buy a used 2001 3.4L engine with 90k on it.. Its compression is 150 on all 6 cylinders.. Is that good? Thanks

If its consistent on all cylinders i would say that is good.. I think when i did my comp test on my 3.4 it was also near 150psi.

My Haynes says, @ 250 rpm 218 is standard and 145 is minimum.
