She was smoking BAD, but once I did a ACCURATE Compression test, with a little help from a buddy turning the ignition behind the wheel, wheile I read the highest achieved PSI reading per cylinder.. #1 was 0 PSI, While the rest where within spec, BUT, there cannot be a 20% difference between neighboring cylinders. **Also, its a good rule of thumb, thaty ur PSI numbers hould not be the same across the board for a back to back series of cylinders.. Meaning, for example: I'll use my numbers as a example..The odd numbers are all on the right bank as your facing the Z, see how 1 is obviously bad, but how my #3, and #5 are matching.. Thats a NO NO... There should be slight psi differences in a good motor, those matching numbers, PLUS my obvious #1 being 0, shows that I most like have damaged PISTON rings, or a burned hole in one or all cylinders on the right bank primarily.. #1: 0 PSI** #2: 148PSI #3: 132PSI** #4: 157PSI #5: 132PSI** #6: 143 PSI. ~M.
