Oil on Spark Plug Threads?
Hey guys,
I recently rebuilt my throttle actuators as a preventative measure, and changed the spark plugs while everything was apart.
While the car was and is running fine, I noticed oil in the threads of all of the spark plugs. I looked into the spark plug tubes that I could see into and didn't see any oil accumulation within.
From what I have read, this may be due to a valve cover gasket leak. I don't seem to be burning oil excessively, as I haven't had to add any oil over the past 4,000 miles or so.
I just wanted to see if this is a worrisome sign that should be addressed asap, or if this is common and relatively benign.
I appreciate any input/further information.
