186,180,160,160

The number 2 sparkplug had oil on the threads. Would this be enough to cause me to fail emissions at idle? The compression was 180 in this cylinder.

I'm sure I could have got a higher reading for the last 2 if I had cranked more.

It shouldnt cause any emissions failure, i had 145 146 152 150 on my last KA and passed emmisions without a problem. It used to smoke at start up but once warmed up, you could turn it on and off without a single puff of smoke
