2002 Nissan Altima

I have a 2002 Nissan Altima/2.5. I keep having problems with one of my Spark plugs getting wet by oil. I have changed the same plug twice. But it continue to keep getting wet. I called the dealer and other parts stores. But no one can tell me what may be causing the oil to get to the spark plug. Maybe you could help me.

Thanks in Advance.

You probably have leakage getting through the spark plug tube seals. #4 on the diagram.

To fix it, you need to but and replace the valve cover gasket (set?), the tubes and tube seals from the dealer. I do not believe thaey are available after market.
