Compression test help..
Just bough a 2002 5.3...doing a compression test with results that are freaking me out...hope im doing it wrong...only have done them on sbc figured was the same..here are the variables..
all plugs out, throttle body valve open, cycling starter through 4-5 complete strokes (more doesnt seem to raise it) ive got 45 psi in the cylinders, 60psi in three more, 10psi in one and 80psi in the other...i know there is some oil in motor but not sure how much because the dip stick is missing (not sure if that matters) also i dont have any of the harness hooked up buy dont think that matters either..
Can some one please chime in and tell me im a dumb a@# and doing it wrong?
