Hi All,
I'm struggling to understand what could be going on with my engine. Two spark plugs on the cylinders closest to the firewall (L & R) have a lot of oil on the threads but not on the electrodes. I only changed the plugs <100 miles ago and already there is oil on the threads again....but only on two cylinders. Even stranger is that I get no smoke on startup or driving.
I'm going to do a compression test this week to see if maybe the piston rings are worn and maybe slinging excess oil up to the spark plugs and its creeping up into the threads, but I would assume that I would see some smoke...?
