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?

The valve cover gasket needs to be replaced cause it is leaking oil into the sparkplug well. This is a common problem.
