When i first bought the car 2 years ago and changed the plugs. I noticed that there was some oil on the tip of 2 of the spark plugs. It didn't bother me too much then. A year later i changed the plugs again and there was oil on 2 of the plugs. On the thread and on the ground tips. Just recently I changed the spark plugs again, but this time, the same two plugs were dripping oil. the threads and the ground tip was covered in oil.
can anyone point me into a possible direction as to why this is happening? I originally thought it was the valve cover gasket (spark plug gromets) but wouldn't it leak oil on top of the spark plugs if that was the case? There's oil on the tip of the plugs which suggests to me that oil is leaking into the combustion chambers. I did a compression test awhile ago and the numbers aren't totally off. unfortunitely i dont' have those numbers anymore (lost them). if it helps you find my problem i can do another compression test.

i would have to say it is your valve seal grommets, i had a problem like that,the reason your plugs have oil on the bottom of them is while you are screwing them out the oil that set on top of them leaks past when you pull them out . does your spark plug socket have oil in side it after you pull the two plugs? if it does then i would say that is your problem..........

HELP A GIRL OUT! ps, you still might be right though becuase i was kindda thinking the same. If the oil came from the inside it would be some sort of leak that would show up in the compression test. i think i'm gonna pull the cover later this week to take a look at it, and while i'm at it, i might paint the valve cover.
