Default 05 Catch Can With Or Without PCV?

Got a Radix on an 05 with the PCV-less system. They stopped using a PCV valve and have a fixed orifice on the passenger side.

Has anyone needed to add a valve inline to the can because of the blower?

Same here. Running a catch can off both valve covers and no PCV. Works great.

Great, It's a

"If It's Not Broken, Don't Fix It situation for me.

I have not seen any problems but have been reading on it and wanted to know if anyone else had any.

So you guys basically just ran the passenger side stock, or valve cover to intake and drivers from valve cover, to can, to intake.

So its a circle, air from intake to passenger side valve cover, through engine, up through drivers valve cover, This is where i will put a catch can, then back to the intake, no more oil.

That may work with a magna-charger but not with a turbo or pro-charger. It will need a one-way valve in the line to keep boost out of the crankcase.
