What to do with PCV valve hose?

OK so I posted this question already on the general forum when I should've posted here. (Original Post Link At The Bottom)

So im building my turbo kit have everything mocked up besides the driver side PCV hose that is under the compressor (The hose that connects to the intake boot originally). You'll see my set up through this link that it's not a kit from a manufacturer. I sourced/"fabricated?" most of the throttle body piping myself. I just have this hose sitting there and I don't know what to do with it. You can see that I already have a catch can for the rear PCV valve. But I don't know what to do with the front one. LMK thank you guys, yall are clutch!

Bubba says to run it into the other one.

Or, cork it off.

That's your CCV Hose first off.

Secondly - run it through a catch can and vent to atmosphere (VTA)

You don't want to cork that off

Connect it to the turbo inlet pipe, between filter and compressor. It's important that this sees vaccum and is not vented to atmosphere or worse, corked.

That is your fresh air inlet for your PCV system. It is to be vented to atmosphere. There are different ways to do that. Factory is in the atmosphere pressure area of the intake, after filter before throttle body. Yours would be after filter before turbo as stated above. If you are concerned about oil blow by during boost you could vent to atmosphere with its own filter or run it through a catch can.

So what I did was buy a breather filter or whatever it’s called and connected it to the “CCV” Hose and tightened it with the o ring clamps. The rear PCV is connected to a catch can.

If you're going for high boost pressure, oil WILL be coming out of that. I filtered mine and it was fine at 300whp and 15 PSI. Going into the mid to high 20s and it needed a catchcan.

Definitely do not cork or route back through the intake as OEM has it.

That is a terrible description on how to set up engine ventilation. Remember on a boosted car after the throttle body is under pressure when on boost. Not like a NA car where it is just atmospheric. This means you need a check valve to keep intake boost from pressurizing the crank case.
