    Default Compression test results

    I got 150psi on all cylinders.

    355 11 to 1 comp.

    236/244 598 614 if it matters.

    Dry test.

    Seem normal? I hear it's not about the number it's about consistency.

    Also engine was cold, sat for a few days 60 degrees out. I did test one cylinder a few days ago when it was 85 degrees out it was at 180 same cylinder was 150 today but with a different tester.

    I have had a cheap tester from AutoZone read low. Borrowed a high dollar one and there was like a 40 psi difference. What I would be most concerned about is making sure there is not a huge variance between the highest and lowest cylinder.

    Your numbers seem ok to me. The valve events also have a huge influence on the cylinder pressure. On my neighbors olds engine we bump the cam timing I want to say right around like 4° and it dropped the cylinder pressure from 190 down to 155 160.
