Oil Fouled Plugs

Asked by May 30, 2014 at 09:03 AM about the Chevrolet C/K 1500

Question type: Maintenance & Repair

I have a 1999 Chevy C-150 with a 5.0. I was changing plugs after a misfire code and found most of my spark plugs where covered in oil. Is it the Valve cover gaskets or do I need new head gaskets or heads

Is the oil external to the plug or fouled on the electrode? Oil external could be a Valve cover gasket.
