Oil and gas in spark plug well. What are possible causes?
I know this is bad, whatever the cause may be. Just wondering what could be the cause. Please and thank you. 3vze 93

Yes, mostly on the head, maybe a tiny amount on the threads. It smells like gas, but it's oily too. Some people have said it could be a head gasket. Is that possible? I think valve cover gaskets would be easier to do myself.

I can't see any leaking immediately around the valve covers. Would it still be able to leak internally into the spark plug wells?
