oil issue

I am looking for some insight into an oil issue i am having. The car has a new short block from subaru....with about 8000 miles on it. Cobb tuned stage 2 with aftermarket perrin intake. The car has always used some oil but recently is consuming an excessive amount which is blowing out the exhaust. My fist thought was turbo seals but after review, they are in acceptable condition. There is a lot of oil in the intercooler hose. After further investigation, it was determined that oil is pushing up the turbo drain line and not allowing the oil from the turbo to drain. My assumption is that its forcing it past the seals and into the intake. Hoping someone may have an idea on why the crankcase is building so much pressure. I checke all the breather lines and there are no obstructions. PCV vale seems to be flowing like it should. Any ideas are appreciated.
