stage 3 apr need help. (Yippers)

the pipe coming from my valve cover that goes into the intake that is right befor the turbo is shooting oil into the intake pipe. Is that because the breather is faulty and not filtering the oil out. Do I need to replace that or is there some other reason. Dont really know what to do. Thanks

That is a one of the PVC lines. A little oil is normal. Alot isn't good as it doesn't burn easily

and can lead to misfires, etc. Is it a lot?

The valve at the intake is supposed to be a one way valve. The oil getting that far is more likely

an issue than the valve itself. There is also a check valve over by the oil filter that is supposed to keep crankcase vapors running into the intake manifold (another pvc valve there) when you are under vacuum and then close when you go to boost. This is to prevent the crankcase from being pressurized. When that check valve 'switches' on boost, the vapors are drawn thru the line that runs to the airbox to turbo inlet hose and thru the pvc valve located there. If you are getting excessive oil running into the inlet hose, I would suspect the check valve isn't preventing pressure from reaching the crankcase thru the other line.
You can also add a 'catch can' between the check valve and the turbo inlet hose's pcv valve to seperate the oil from the vapor. If you do a search of the forums you'll see several discussions on catch cans.
