1 Answer

The most common causes are failing oil seals in the head (s) or failing piston, oil rings. Esp. if this is a high mileaage vehicle. There are adaptors you can purchase to install your spark plugs into , then into the head, but it's really only a bandage for a potentially bigger problem in the engine.
