your mainly looking for consistency when doing a compression test. my old DE did 180 psi across and my VE does something crazy like 240 or something. i forget i cant remember the exact number. but they were very consistent. find out what its supposed to be in the service manual, and if its within a few numbers in each cylinder your in great shape.

Also make sure your engine is at operating temperature and your throttle plate is all the way open while doing a compression test...
