Dutchhotrod, I just ripped apart a brand new 406 with less than 500 miles on it. My engine was doing the same thing but worse. Anyway, the motor was sucking oil through the PCV valve. The blower was soaked inside and the intake was walloring in oil. When I pulled the intake, each intake valve that was closed had about a tablespoon of oil in the port. Major bummer. Oh well, live and learn, it's only money!
