Still getting more oil in the catch can than I feel should be in there, so, I decided to compression test the engine. Swap vehicle with Ls7 NA with cam, long tubes, MSD Intake. Performed the test on a cold engine. Cranked the engine 5 cranks, got out and recorded the number on the guage. I did note that all cylinders seemed to hold the reading quiet well. As in, I viewed the reading for roughly 3-5 seconds to see how quickly the readings would fall, if any. My approach may be flawed, so, I am open to any pointers you may have. I also, do not know what psi is supposed to be for a healthy engine. Internet searches show a large variance. I have attached pictures of the spark plugs as well. I should note: the plugs do not have oil on the threads, that is anti-sieze.
Thanks.
