Drivers side oil separator with a Whipple

[sigintel]

I was thinking remove the check valve in the standard UPR setup.
That is only IF Whipple passenger line is PCV only and no check valve.
Just looking for any flow differences with UPR vs Whipple.
Thinkn maybe UPR check valve might limit flow and hold higher vac.
Dunno.
Thanks for your thoughts on this.

IF you are referring to the line in this picture. I would leave it s is with their catch can. It sounds vital for it to do its job correctly.

there is a one way check valve in that hose, it is directional and has an arrow for correct installation.
