Jason answered about a year ago
if oil on plugs there could be cracked plugs. i've put rubber hose piece in my socket to help keep the plug straight and avoid cracking the plug. also, are u torque-ing the plug at proper tightness? are valve cover seals ok?
Bob answered about a year ago
The valve cover gasket needs to be replaced cause it is leaking oil into the sparkplug well. This is a common problem.
