Out of curiosity while checking the look of my spark plugs, I decided to run a cylinder compression check on my 18GK engine. I had the head rebuilt and installed a new head gasket just under 1500 miles ago. I retorqued the head bolts not long after re-installing everything.
Test results twice per cylinder. Engine cranked without spark plugs until oil pressure gauge showed a reading. Engine was cold.
#1 145 140
#2 135 130
#3 135 135
#4 145 140
I don't suspect that anything's wrong, but am curious how these numbers stack up against what everyone else sees on their cars.
Thank you,
