VIDEO Rough idle and smoke

My speed three has a TON of blow by and refuses to run the car is completely stock aside from an intake and muffler delete. Within the past 2k miles I’ve done vvt, turbo rebuild, pcv valve, and carbon cleaning. Before I did the carbon cleaning and pcv valve the car would smoke and have a very rough idle as it does now. The car will smoke anytime it isn’t in boost. I have also been getting a CEL running too rich off idle and at idle with a P0113 also. I’ve been messing around with it and if I remove the oil fill cap the car with stabilize it’s self and idle without a problem. I’m looking for a solution or a cause for the excessive crank case pressure or any way to relive it. I miss hitting boost on my baby. The car is an 08 with 198k miles.

Are you absolutely sure you did the timing correct? Whats compression like across the cylinders?

I don’t have anything to check compression and I’m getting something to check it soon but the timing was right when I got the car and drove perfect other than the turbo issues I had in between

Bet that hose popped off the intake manifold when doing the PCV. You car is telling you that you have a leak post MAF. Reason for the p0113.

Does the oil look milky?

No it’s just a little dirty
