I went through a few threads in the search, but found nothing.

My question is, I changed my plugs the other night and there is fresh engine oil on them. Any Idea what could be causing this? The car runs good, exept for the bogging below 2K. I'm not sure if it was just oil in the spark plug holes from a leaking valve cover gasket, or something else. The gasket looks allright at this time, but there was oil along the top of the valve cover, so I will be changing it. Assuming there was oil on the electrode, what could be the problem?


I have new Denso plugs, Ford wires, fuel filter, K&N drop in filter and waynes tune. I hooked it up to the scanner at work and there are no codes.

Thanks for any help[:D]

More than likely, it is what you think, oil that has seeped down from the gasket. If there was oil in the combustion chamber it would burn off and look black and shiny on the plug electrode. Thats just a guess since I can't see the plug, but if you have no blueish smoke on startup or hard acceleration, its prolly a leak somewhere.

Im in the same boat as you my friend. Valve cover has been done three times. Its valve seals. Its not leaking from the top, its actually being pushed up from compression. When I was NA, it was minimal pooling, now with FI it was a damn lake. Tonight, I thought for sure I blew my motor. My car sounded like a Subaru. I pulled the plugs, and washed em down with brake cleaner. Still rough. Put the OEM coil and wires on, still rough. I feared the worst and decided to go home (I was at my mother in-laws). I started my car, went inside to say "I'll be back" to my wife and from int he house I heard my idle change. Went out hit the gas - perfect.

On August 12th, 'crazymechanic' is coming to do my seals. Requires cam removal. He had the same issue and he said valve seals cured it.

You can replace the valve cover gasket all you want, but its valve seals...

...do a compression test too...just to be sure.

Mines worst at #1....how bout you?

I had oil all over plugs 1 and 2, replaced the valve cover gasket, no problems for about 7 months now. Valve cover gasket only cost $15 and takes half an hour. Seals, are a bigger hassle and cost more.

GRRR that damned valve cover gasket has leaked on me a thousand times! Make sure you replace the GROMMETS when you do the gasket- 99% of the time it is just the grommets leaking and some gaskets don't come with the grommets.
