: Moisture around spark plug well

08-15-07, 03:00 PM
I have some moisture around one of the spark plugs (in the spark plug well). I can't determine what liquid it is, looks like clean oil. Car has not been driven for 2 weeks and it is still there so assuem its oil. Could this be a big problem? Is it possible for something to come out of the cyclinder head through the spark plug thread or could this be moisture, possibly oil leaking from a valve cover and accumulating in the spark plug well?

If it was coming out of cylinder, you would hear all kinds of hi pressure noise. It is coming from valve cover gasket. I have seen that on some of my cars in past, but I do not remember which ones.

Real mechanic might not agree with me.
