Oil in post-intercooler piping? Already have a catch can
 

Hallo.
Trying to figure this out myself, but I just don't understand :sadwavey:

So as some of you may have read my car is off the road right now, and among several things (Since I drove it yesterday, the first time in a week, i'm getting a P0103 and some lean condition code. Though my MAF voltage looks good and so does my airflow? Car runs like crap though.) I'm turbo as well.

I have a catch can, and it doesn't vent back into the intake, just a breather. But I pulled off the upper IC pipe (Connecting to the TB) And there was a pretty sizeable puddle of oil on the connector, and traces of oil all the way down to the intercooler. So, scratching my beard in a furry, I decided to pull of the turbo-side piping, but that's clean as a whistle. So that sort of ruled out my turbo failure idea. And I don't have my ventilation routed back into my intake, so where is this oil coming from?

from the engine--check and see if your catch can is plugged
is the catch can to vacuum?
you may have had the engine too full of oil and it puke back.
we fill not to the top anymore --just a little down pass it.
