Oil coming from spark plug hole???

Hey guys,

My car has been smoking for the last few days from under the hood (the smell of oil on the exhaust). Well, after thinking that I had a valve cover leak, I got out and watched the motor as it was running and saw oil dripping down from the spark plug boot and onto the header. I also saw the spark plug from that same boot kinda wiggling around slightly...obviously it needs to be tightened which I will do when it cools down, but should oil be coming outta there? Thanks!

um, no. If the cylinder has that much oil that its pushing past the plug threads, you've probably got other issues. Are your plugs oil fouled, or do you have oil burn problems?

Well, just did an oil change about a week ago and just had to add half a quart already. When I pulled the plug, there wasn't that much oil buildup on the electrode, it was a little black - but not drenched in oil. There was more oil and sludge buildup on the threads of the plug. Kinda confused - this doesn't look good, huh?

No reason 2 B confused..If oil was seeping/coming out of the plug hole the cylinder would probably B DEAD(Dead miss).Obviously the gasket is leaking & slowly running down into the plug hole or some blowby is misting a small amount of oil out the spout & running down to plug hole!!!A 3D choice(MOST LIKELY) would B someone was filling oil through the oil fill spout & spilled some..I'd check the rest of the Spark plugs & make sure they r tight also!!!

Does the car burn oil, as in, blue smoke out the tail pipes? If not, then its probably coming from the valve cover, or like midnightrider said, could be some that spilled a little while filling. Also, if you had ring, or valve guides/seals to leak that much oil out, you would be burning a ton of oil and would be smoking(out the tailpipes) like crazy.
