Re: NOTE

Hi Duff5000.
Regardless of it ' getting a little higher ' your engine is in need of a bottom-end rebuild. New crank bushings. New rod bushings. New rings. A functioning and cleaned oil punp at the sump. Do the work yourself and you'll save at least a thousand dollars or more. Goodluck. shane-

Sorry...

Hi Duff5000.
Sorry but compression at 90lbs indicates a rebuild to me. If your engines compression is staying at 120lbs then it is still a weak engine and may run for 50thousand more miles but will probably die the death of a broken rod or a broken crank. Unless I misread your original post that indicated 70lbs and 90lbs as a steady state condition then the belief that it was rebuild 30thousand miles ago was presented to you falsely. Someone lied. The only way a rebuilt engine with 150 and above compression drops to 70lbs and 90lbs is to have been seriously abused. Again, my 02 is for you to attempt the bottom-end rebuild. Goodluck. shane-
