With a proper catch can setup, the crank case vent is still connected to the air filter box, then you replace the PCV valve on the head with a simple nipple connected to your catch van via a hose. The PCV valve should be moved to the outlet of the catch can to prevent pressurizing the catch can when under boost. From the catch can a hose goes to the intake manifold like normal.

Since most PCV valves leak on turbo cars we end up with a slight positive pressure in the crank case under boost and this back flows out the vent connection into the air inlet hose leading to the turbo crapping it up with oil, water vapor, and blowby gases. .

this is what a catch can does
