Oil puddle in intake.

Cleaned MAS and Throttle body last night. Found puddle of oil in bottom of plastic intake chamber where throttle body attaches.
Seems to be coming from uppermost hose that attaches to chamber on drivers side....looks like it might head to PCV valve but does not really line up with it (dissapears under intake).

Any ideas?

Used CRC Brakeclean on MAS, no ill effects, seemed to fix the cold engine weirdness.

Thanks.

The oil is condensed from crankcase vapors. It is very normal in EFI manifolds.
