I've had several boosted cars and I'm never seen anything like this. I have a procharger at 7 PSI did a second gear pull smoke poured out from under the car and started dripping oil pretty bad.

I narrowed it down to the leak coming from behind the crank so I drove in took everything apart assumed it was probably the crank seal but was hoping that it wasn't the upper oil pan. When I pulled the pulley off the seal came completely off with the pulley so it had pushed all the way out of the front housing.

. I was wondering if anyone else has experienced anything like that and if so how they fixed it. I'm going to be doing a lot of work on crankcase ventilation cuz that's the only thing I could see pushing. See you all the way out. Any advice or help while the car is torn down let me know

 

Venting may help, but it's just a band aid. You've got a lot of blow-by. Before you go much further, I'd do a compression test and a leak down.
