In my view, there really shouldn't be much oil in this pipe anyway! Although I have changed mine, I think the bigger issue is the amount of oil getting to this section - I have fears it could be my turbo seals/bearings passing oil and therefore probably in need of a rebuild and/or the crankcase breather is allowing too much oil into the air intake. I think the latter is the most probable cause due to the poor separation of air/oil in the E90s.
