I was changing my spark plugs and i noticed one of them has oil on it. is that normal? I know i have an oil leak somewhere in my engine but i couldn't locate it. It wasn't the valve cover gasket. Any clue how oil might have got to the spark plug? thanks

 

go get a valve cover gasket kit it will come with the valve cover gasket all graumits you need and the " sparkplug O rings " you have to take off the valve cover, flip the valve cover over and you'll see the rings that you need to replace. they keep the oil in the head from going down into your spark plugs. i hope that helps
