Recently pulled the Autolites out of the car to replace with NGK's. (I know. Autolites...WHY?) Anyhow, the Autolites have about 4,000 miles on them. The electrodes and insulator look great. Very clean, etc. They look practically brand new.

Problem: There was oil on the threads of the plugs. All four plugs. There was no oil on the electrodes, insulator, within the plug canals, or near the rocker gasket. Only on the actually plug threads.

Any idea's?? I do not think I should be concerned, but just need some more ideas to why it happened.

Oh, I also just replaced my PVC due to it being completely clogged and the valve was stuck.

Probably some bad plug gaskets. They are cheap, like $1.35 each? Pull the valve cover off and replace the gaskets.

Actually, just replaced the rocker gaskets about the same time. 4,000 miles ago when I did the 91 intake cam swap.

So it can't be that. There was no oil on the wires, just the threads of the plugs themselves.

there is a gasket for the valve cover and then individual ones for the spark plug holes as well.

Did you only replace the vavle cover gasket perhaps?

 

[NismoPC]

I replaced both gaskets. The rocker cover gasket and the plug gasket. The plug gasket is a one piece gasket, not individual gaskets per hole. The two came as a kit directly from the dealer.

Here is the thing. There is NO oil inside the four chambers, canals, tubes, whatever you want to call them where the wires are inserted. There is NO oil on the wires themselves. So the oil is not leaking from the gaskets.

From what you said, I don't think it is a problem. No smoke? If there is no smoke and no oil on the plug (the parts inside the cylinder), then I wouldn't worry about it.

Do you think someone might have used oil instead of antiseize compound on the plug threads?

Maybe it was just residue from before? Or does it look fresh?

No smoke.

Hey Jason, these are the cheap Autolites you and I picked up at Advance Auto when we installed the cam. I finally got around to replacing them.

This was fresh oil. Didn't even look discolored. Funny thing is I changed my oil about 3000 miles ago and it's do again.
