1999 Plymouth Breeze Question: Oil in Spark Plug Tube
Replace the valve cover gasket. You might want to replace the plug wires to. Rubber and oil don't go together well. - backyard tech
Not only should you replace the Valve Cover Gasket, you should also change the Spark Plug Tube Seals. This would save you some extra cash down the road. The seals degrade over time and allow oil in the spark plug tubes. This would contaminate the rubber Plug Wires and potentially cause them to fail, the engine to misfire, and decrease fuel economy. You will know that the seals need to me changed if the plug boots have oil on them. Generally the seals should come with the new Valve Covers Gasket in a set. If not, its worth the investment. - Visitor
