Compression Test Results (Am I okay?)
I performed a compression on my engine last night for s***s and giggles. I let the engine warm up to 180 degrees, shut it down, removed the plugs, disconnected the fuel injectors, and tied the throttle open at WOT. I got the following readings. Cylinder 1 (196), 2 (199), 3 (197), 4 (197), 5 (212), 6 (218), 7 (216), 8 (215).
As you can see the Passenger's side bank although fairly consistent is different from the driver's side bank which is also fairly consistent. I also noted that on the first stroke the compression for each cylinder was between 110 and 120 psi and the needle moved rapidly throughout each compression until maxing. I never went for more than 6 compression strokes.
Is it normal for the 2 banks to have differing compression rates? Am I missing something? I did timing chain work a few months ago (tensioner on driver's side went bad and chain jumped a tooth.

I think that's okay, especially because all of the lower numbers are on one bank.
they are definitely better than my numbers. lol i pulled 90 and 145 on a couple of my cylinders but that is being addressed.
