I have oil in the spark plug cylinder where the spark plug cap goes on to the spark plug. The cap goes about 4" into the top of the cylinder. Only the one cylinder has oil in it.
The cylinder where the spark plug wire cap, which is about 4" long, goes into the top of the engine to go on to of the spark plug, has oil in it. The other three spark plug cap cylinders are fine.

That is part of the valve cover. There are 4 round seals that keep oil out of the spark plug wells. If you get a new valve cover gasket it will come with them.
