Turbo leak? Crankcase breather leak?? Help! M57 330d

So trying to chase down an oil leak...so far changed the common red intercooler flex pipe which had oil seeping through. But the oil is in the turbo intake hose after the MAF too. That also has the crankcase breather hose connected to it and there is a thick coating of fresh oil from that breather into the main turbo intake.

At first I thought is it my turbo on its way? There is some play in the compressor turbine but what are the limits? Also, why am I getting what seems to be excess oil through the breather? I've looked into this and doesn't seem to be an issue with the breather itself. It's the rubber diaphragm type and seems to in good working order.

I just don't understand what's going on.
