Crankcase evacuation issue...
Car has been using oil at a decent rate in boost. Compression and leakdown are good, not a lot of miles on a fresh build. PCV was hooked up just like stock with the valvecover vent going to the intake on the turbo suction side. I removed the intake manifold where I found oil pooling from the PCV line. I figured disconnecting the PCV alltogether and venting it to atmosphere while leaving the valve cover vent going to the turbo suction would be a simple solution. In doing so, it seems oil consumption has dropped considerably but I have a very large accumulation of a milky thick sludge and water vapor in the line going to the valve cover vent. No evidence of this is in the engine itself. Is this just from a lack of crankcase vac? A mixture of oil and water vapor from the lack of PCV system? Will a catch can solve all these issues or do I have something else worse at hand?

Re: Crankcase evacuation issue...
I would run the vent hoses coming off the valve cover to a catch can... once you have a catch can setup you will be disgusted when you see what all is going into your intercooler, piping, and turbo. The only venting I have is two hoses coming off of the valve cover running to a catchcan. It gets half way full every 3 or 4 months.
The milky sludge is more than likely moisture in the hoses from the heat escaping the engine combined with this cold *** weather. Ive noticed this before on my car as well.

i dont know why everyone is continuing to beat on the no drain back setup when it has been beaten to death the fact that it is not a problem at all. t1 clearly justified that it is fine to have a catch can oil return.
you should get a catch can with 2 vents off the front of the valve cover (the front of the valve cover has 2 baffles or you can go off the back of the valve cover but you will need to add a baffle on the inside of the valve cover) and have atleast 1 return to the back of the block.

EDIT: also, this is on a single cam engine... so I don't know if the "dual baffles in the front" theroy would apply. I will check into it today since I have a spare valve cover I can check out.
