Oil on number 3 spark plug
Truck started missing, pulled the codes, found miss on No. 3. Pulled the plug and the threads were covered in oil. Wiped it off and put it back and it runs fine. But where could this oil be coming from? Valve cover gasket? Bad piston ring?

if the threads were covered with oil , then it sounds like leaky valve covers .
If the oil came from the top ( because the oil was on ONLY the threads and NOT the electrode area ) , then , more than likely I would check your valve cover gaskets first ...
