I just did a little cleanup around the CCV breather this morning. Like Chirpz says, these small leaks on top of the engine create puddles/pools of oil hidden by the engine insulation foam. Eventually the pool/puddle is full and the oil makes its way down the bell housing.
do a thorough cleaning of the top end around the turbo base and the CCV breather. to clean the top end, I used the wand at the car wash to spray hot soapy water in an opening near the front radiator hose, you can just see the front of the oil cooler on top of the engine. this flushes hot soapy water passed the oil cooler and then passed the base of the turbo. I flushed mine well and made it spotless and then cleaned the bell housing and I watch it carefully afterward.
supposedly there is a oil drain hole near the base of the turbo that exits below the bell housing too.
