Hi guys, I've been using lots of oil (topping up approx 1.5litres per month) recently. Last night i decided to check the compression of each cylinder, and found i was down a fair bit on 2 cylinders compared to the others. Im not entirely sure what readings to expect but the results i found were as follows,
170PSI on 2,
155PSI on 1
145PSI on 1
Could anyone please advise me as to what i should be expecting to find? Car is a 2003 BAM engine, REVO stage 1.
