Right done a compression test on me saph 4x4 cos today, STD engine internals running stage 3. Got the following results:
Cyl 1 11bar
Cyl 2 11bar
Cyl 3 11bar
Cyl 4 10bar
Should i be worried about pot 4 losing 1bar, got a gut instinct its the headgasket, intermittent missfire after first starting, just reconned the rad as end caps leaking. Also @ 11bar must be STD compression right?
Cheers Bri.
