Hi gang. Over here from the 48-60 group. I have a 2008 F-150 with a 4.6 SOHC engine. Had a miss in cyl 5. Investigated and found oil in the well of spark plug when I removed my COP. Obvious cause of miss fire. Want to remove and replace valve cover gasket. Any suggestions would be greatly appreciated. Big Job? Little Job? Also, how to remove oil from Spark p[lug well. Plug it self has NOT been removed.
