Correction - It is the valve cover gasket that I suspect is leaking oil into the spark plug well NOT the head gasket as initially posted. I will tighten the valve cover bolts tonight and go from there. Thanks for all of your input.

I've never owned a 4.6, but I swear that the plugs are different (for a reason) between the two banks.
