Quick question - I have upsized my breather outlets to 1/2' (-10) recently and are using dual Radium catch cans. The Radium PCV is installed on the catch can side which routes to IM. I am noticing that I am filling up the catch can now where as before with the older cover OEM breathers, I hardly had anything using OEM PCV. I posed the question to Radium and they said perhaps I need to consider my baffling. Given larger size breathers, do I need steel wool scrubbers in my baffles? I did make the opening larger between cold and hot side baffle (based on advice here). I am non Forced injection with built motor. I am filling up oil during long idle - have not been on track yet with new setup.
Seeking your guidance.. Thank you all.

 

In reference to this setup. Can I leave in the pcv valve and connect both breathers on Crank case to a vented catch can and block the IM?

Or does the valve itself need to go?

 

You can have all three lines into the valve cover. There is nothing too preclude that. It would work fine.

 

If I understand what you are asking, then the pcv valve is not needed. If both sides of the valve cover are connected to a vented can and the can is not connected to the intake at all then the pcv valve serves no purpose and can be removed.
