I completed a first compression test because of a cooling issue I was having and wasn't pleased with the compression results. For the time being I believe I've solved the cooling issue and do not believe it was in result of the compression #s. Also I haven't found any smoking, stumbling, misfires, or CELs. It runs solid and feels generally strong.
Tonight I've completed my second compression test with a warm engine / WOT which I didn't do for the first test and results changed to be a little more consistent.
#1 170
#2 168
#3 160
#4 165
#5 135
#6 135
#7 130
#8 138
Passenger bank is good, driver bank is all low. With no other indications (smoking misfires ect) is it still possible my engine has four damaged piston/rings all within that close of each other in compression on the same bank? Should I be thinking there's a timing issue here instead? I've read something of these cars "skipping a tooth" messing up the timing?
Hoping I can be schooled in what I'm seeing with these results and where to go from here.
