    Hello, I had made a post a few weeks ago about doing a compression test. Different tests were thrown at me, but since I had already purchased the compression test I went ahead and ran it. I did the test cold because I didn’t want to mess up the threads on the engine. I did not have the throttle engaged but my numbers came out to 155 psi on 5 cylinders and 160 on one! Is this good numbers?

    Those are excellent numbers even though you have a five psi difference between the other cylinders from one those pressures are awesome

    Those are fine, don't worry about the 5 psi difference

    5 psi is well within the margin of error. You are fine.
