  1. If oil is leaking in externally, wash it with brake wash and install new plugs, run engine and watch to see where it is leaking from and repair as needed.

    If oil is getting into the spark plugs internally, the most common reason would be valve seals. Have them replaced if your compression is OK. http://freeautomechanic.com/what-is-compression-test.html
