just got new spark plugs wanted to make sure they are the correct ones in the book there were two numver ap 104s and ap 764s...i got the 104s is this fine?
make sure you torque them correctly, and again in a few hundred miles or so. i guess i skipped one on the second pass of torqueing and ended up blowing it out of my head. costs a pretty penny to fix...
Just wanted to ask a related question. I'm changing my sparkies today and the first one I pulled out wasn't too bad except the fact that it has a small amount of oil deposit on the base of the plug. What does this usually mean? Could it be the PCV value or something? I would be surprised if it was some sort of seal leaking on my engine at 81k miles. Thanks,
