About 3 or 4 of my spark plugs seem to foul just at about 1 month for the past 3 months, I can tell when they go because it will stutter like crazy and have no power. When I pull them to check, I noticed they are covered in oil. Where do you think this oil is coming from and how to fix it? Its not the valve seals is it?
