When doing a compression test on a 7.3 do you...
After reading some scary stories of Compression numbers, I realized I never tested mine. Had 122,000 mi when I got it, has 184,000 mi now. Runs fun but you never know.
Anyways, when testing on these motors, all GP's out, is it best to disconnect the main UVCH connector or each injector connector when doing the test. Is there anything else that needs to be DC'd for the test? Was stock compression 400psi or 450psi?
