Not all have this issue based on the amount of oil some others have collected. It seems to be random. As SC2150 said, it appears there is a problem with the intergrated PCV baffle and the cover.
My service invoice states.
Customer advises he has a catch can on PCV system. Customer is catching an ounce every 300 miles. ADVISE
Valley cover
remove throttle body and inspect found excessive oil in intake suspect valley cover leaking. Remove intake ans replace valley reinstall intake.
