Yet another oil spill

Greetings, everyone! I just bought a 2014 Gran Coupe for 106k. After getting home, I took my time looking at it. Lesson learned: be cautious when buying from a stranger.
Anyway, I wish I had taken pictures before I cleaned up the oil leak at the front of the car, because it misted the entire inside of the engine bay. From what I can tell, there's oil around the intercooler pipe and the crankcase breather pipe. I'm crossing my fingers that it's just the seals on the crankcase breather that have gone. Did anyone else experience anything similar?So far, I haven't noticed any leaks near the turbo or the rocker cover.
Thank you
Is it possible for oil to be blown around the engine bay from a split intercooler pipe? I don't see any cracks, but I cleaned it all up anyway.

Indeed, oil mist can be sprayed about using a spit boost hose.

It was my assumption that the oil was on the charge hose, but now I'm crossing my fingers that it's actually coming from the crankcase breather pipe. To find out if they have any in stock, I will be calling BMW tomorrow.

Breather pipes are always on hand because of how often they crack on N47 and N57 engines.
