Oil in Intake problem????

Here it is. I have oil in my boost solenoid, intercooler and throttle body. I think its coming from the pcv fitting right on top of the crank case underneith the inercooler hose. That pcv hose connects into the intake hose right before the turbo. I already installed an oil catch can, but that just ties into the lines that come off the valve covers right? Or did I install it wrong and it is suppose to come off the pcv fitting on top of the crank case? If any one knows help please.

Thanks, T

Its normal, they design the turbo to leak oil some. I heard it had smoehting to do with smog but I think its more like loose tolerence on th bushing. Hope this helps

Thanks, but I'm running a VF34 @ 19psi. I finally got my computer to work and got some good searches on this issue. I routed my crank case pcv line in to the catch can install. Now I just gotta clean my plugs or get new ones also hope all that oil didnt damage my boost solenoid any ways thanks again for your in put.

It may not be a good idea to run both lines into the the same catch can. They are independent of one another. I have a dual can setup on mine, I get a little oil from the valve cover vent but the PCV is bone dry. Chances are yours is too.
