Hi Guys Ive got an Astra 1.6 petrol with approx 60k on the clock which I bought a few months ago. Car looks immaculate, but dry compression test results are: 1: 215 psi 2: 215 psi 3: 190 psi 4: 230 psi. Would that amount of variation be cause for concern? Car seems to run fine otherwise.

wouldnt bother me. What does number 3 plug look like compared to the others? Tried dropping a bit of oil in the low cylinder and retesting? Have you done a leakdown test? Does it drive ok? Edited by user Thursday, 28 December 2023 9:33:32 PM(UTC)
