I did a compression test on the weekend on my Astra 2.0 16v GTE

I used one of the screw in testers and i got a very simular reading of 190-195 Psi is this a good or a bad thing

:confused:

yes it would, if you suspect rings,do a compression test and note the results, then put 10cc ofoil in the cylinder before doing another test,if the reading stays the smae its not your rings, if it rises though itmore than ikelyis therings as the oil helps seal the piston/bore
