Why Is There Oil around My Spark Plugs?

Answer

Oil around the spark plugs is caused by piston rings or cylinder walls that are badly worn. Oil may also be pulled into the chamber because of excessive clearance in the valve stem guides, or badly worn valve stem seals. This condition can force oil and oil vapours past the rings and valve guides into the combustion chamber.
