Ive never opened an OEM pCV before however the OEM brake booster hose has a 3/8s plastic check valve pellet that goes inside of the hose.
I tend to use this pellet on engine swaps that ask for a small booster hose the pellet does wonders and could help out for the PCV.
Now being that you are boosted I'd suggest to do away with the factory routing. The factory routing will be pushing total boost psi into the check valve which is possibly the reason why they crapped out.
For a boosted setup the ideal setup is one that maintains a vacuum source but not from the intake manifold ( reason why is the strain of the valve)
Many folks end up gutting the PCV valve and route a hollow valve and hose to the inlet of the turbo/SC. Doing it this way will keep the crankcase flowing.
If you plan on using the turbo/sc feed to suck these gasses you wont need a PCV. You can put filters on your breathers and route the PCV hoses to the turbo intake. You can put a catch can in between to filter these gasses so you wont burn them.
