Over time, the grommets that seal the spark plug tubes to the valve cover can harden up due to heat and oil penetration. This can result in oil leaking into the spark plug tubes and also idle problems with the fuel injection due to vacuum leaks. Eventually, oil filling up in the spark plug tubes can reduce performance or even cause the plugs to stop firing. If you go to change your spark plugs and there is oil all over the plugs, the seals are leaking and must be replaced.
