[QUOTE="thomas91169, post: 7615764, member: 40530"] ouch. on a healthy motor, your lowest cylinder should be within 10-15% of your highest cylinder. So if its 180 highest, lowest can be 155. of course, the less of a spread, the healthier and more efficient the motor is. i think around 180psi is good. I have 180psi across on my passenger bank, and drivers bank is 135-155-165-175. Leakdown shows leaking through exhaust, which means i have some burnt exhaust valves on the drivers side. Make sure you are doing the test on a warm motor (unless you dont want to run it), otherwise you cant really **** up a compression test, it either works or it doesnt. Next step is a leakdown test to see exactly what is causing low compression. btw im pretty sure passenger bank is cylinders 1-4 starting from font to firewall, and drivers bank is 5-8 starting from front and ending at the firewall.
