Oil is fouling your spark plugs? Is it all of the plugs or is it just one? Is this something that happened suddenly or has it been slowly building?
The most common cause of spark plug fouling by oil is worn or broken piston rings. This results from wear and tear or perhaps breaking due to lack of lubrication. You could also have a head gasket problem.
