Greetings,
Ford Performance has air oil seperators for both the driver's and passenger side of the engine. Has anyone installed both seperators and do you pick up oil in both seperators?
Thanks,
Tom

 

I don't have my car yet so I am making an educated guess here about the Positive Crankcase Ventalation system on the Ecoboost.

The PCV line to the valve cover is probally connected to the intake pipe. Clean air is drawn into the engine block though it. In theory only condensation will collect in the seperator here. However when the crankcase is pressurized and the solenoid in the line hasn't snapped closed the engine crankcase vapor could back up into the intake pipe and coat the compressor wheel.

The PVC line on the drivers side connecte the crankcase to the intake manifold. Under vacuum the oi vapor will be sucked into the intake manifold to be burned. Oil should be seperated out on this side of the engine. Does anyone know if there is a check valve in the line by the intake manifold to prevent over pressurizing the crankcase and oil seperator under boost?
