There are a few threads on catch cans indicating excessive blow by requiring a check valve. Isn't the PCV a one way valve? Do we really need a check valve if installing a catch can? For those with a check valve what size and where did you get it?

The check valve you can get from Tork. The reason for the valve is to keep the catch can from seeing any boost and protecting it.

So where to put it ? Should it go between the plenum and the catch can ?

It goes where the red arrow is. Flowing the direction of the arrows. Outlet side.

Thanks ! I have to get a 3/8 fitting to attach my add w1 to the intake hose. I'll pick one of these up and that should complete my install .

Here is a link to ours, the issue with alot of the cheaper ones is the cracking pressure is to high which can limit flow. Our are a billet aluminum with viton seals, so never have to worry about clogging.
