Oil Catch Can

[float_6969]

Yea, I asked about this once before, but I didn't really get a clear answer. I got an oil catchcan with my intercooler. After spending a full weekend tearing down, cleaning, and reassembling my intake manifold, I believe in the neccesity of them. The problem I have is that I don't know where it goes. There are two line for the PCV system and I don't know which one it goes inline on. there is one that goes to the manifold and one that goes to the intake for the turbo. So which do I use!?!?!? Thanks.

the one on the left side on the engine nearest the rad goes to the intake manifold, and the one at the abck of the cover on the right hand side goes to the catch can i think..... someone correct me if i am wrong please..

i have alsoe seen setups that both breather hoses go to a T then to the catch can, eliminating the blow0by to enter the intake (which i think is better)

use the one going into the intake of the turbo. this will at least keep it out of your turbo & intercooler.

Well I did some reading in the FSM last night and it states that at low rpms (when the manifold is under a vaccum and the turbo hasn't come into boost yet) the PCV system pulls into the intake. At high rpms, the suction of the turbo inlet is used. I installed it between the RIGHT valve cover and the turbo inlet. I figured that at lower rpms there would be little flow of crankcase gasses (and oil) into the manifold, but at that higher rpms the suction of the turbo would be greater than the manifold vaccum ever would be. We'll see if it works...

Well it's installed. I had the pipe come off a couple of time and the car ran like crap, but I think I've got it on good finally. I haven't seen any oil in the lines yet though...
