Hello everyone,

I found some engine oil sitting in the plug wells when I changed the spark plugs last week. There was more oil on top of some plugs than others, and two or three were clean. My engine does leak/eat about a quart of oil every 2500 miles.

Valve cover gaskets?

It is the plug well "O" ring seal in the cam cover that has seeped a bit. Consider how long and how many miles it took to accumulate. Wipe it out and then do it again next time change the plugs (in another 100K).
