Default pcv "delete" change up with boost setup

I've searched and see a lot of different setups. Here's what I have in mind for my coming setup, would this work.

Basically remove the current pcv stuff and run fab'd valve covers with -6 bulkhead fittings on both covers both running to a breather/catch tank.

would that work sufficiently?

I kept mine stockish. Fresh air is infront of the turbo. I have a catch can and check valve inline between the valve cover and intake.

only reason I was going to get rid of the entire pcv is that I am going with the different valve covers with no provision for the valve.

I see what your saying but putting a constant vac into the valve covers would be best right

Why not put one line from the intake on the turbo filter tube to a catch can where both valve cover -6 hoses connect and a one way check valve in the hose form the turbo.

That way at idle there will be a little vac helping the vent and under load the turbo would cause more vac pulling more from the covers. Both through the catch can making sure the oil doesn't get into the intake turbine on the turbo

Get what I'm saying?

not sure I get what you're saying really. would you do it with a vented catch can or a sealed unit in that instance?

Sealed can if you ran vented it wouldn't have any suction on the motor. A slight vacuum in the crank case is way better than the pressure pushing itself out.

I think I understand what you're saying now, run a line from each valve cover to the tank, then a line from the tank to the intake tube to supply the vaccum to pull from the valve covers, is that about right?

You can make a Venturi in front of the turbo instead of just a fitting. It will create more vacuum. Depending on size.
