I have recently bought an engine from a car breakers. I have just done a compression test by turning the starter motor over by putting a power pack on it . The readings show ( left to right) 10bar. 6bar 7bar 7bar . Is there something I’m doing wrong? I know they’re supposed to be all the same but with it being a bare engine with no exhaust mani gearbox and air filter etc should that affect the results?
If there’s anything you think I’m doing wrong please let me know thanks.
