As I was changing the spark plugs today, I took out the first coil and plug and they were covered with oil. There was small amounts of oil sitting in the low spots of the area above all the spark plugs. I am at a loss for what this could be.

I changed 1 plug and attempted to wipe out all the oil in the area and then started the car. Of course there was some white smoke that burned off the oil at the start but it went away. No smoke on exhaust.

I left all the covers off so I could look and one of the plugs seems to be accumulate small bubbles while running. Since I don't see white smoke, could a gasket be leaking this up to the spark plug?

I took the cover off the other side and there is some oil build up in there as well.

Any ideas what is causing this? Should I just replace all covers and sell vehicle?
