Here is the situation: we bought a trackday kit car powered by Ford Focus ST170 engine with Rotrex supercharger.

First of all I should mention, that my knowledge about this engine is quite limited, since we bought used car in this setup already.

The problem we are experiencing is an excessive amount of oil and air flow coming from the pipe marked on the photo below. (Photo is not from our actual engine)

I guess this is not normal behavior. Any ideas, what could be causing this? Where do start looking for the cause of this problem?
