I am not having any issues currently, but here is my setup with my ESS kit.
I have a breather on the drivers side valve cover.
I have the UPR one way breather on the oil fill cap.
I have a JLT 3.0 catch can on the passenger valve cover to intake, with the PCV intact.

Should I gut the PCV for the catch can? I did have it gutted when i ran just breathers, but put the check valve back in for the catch can.
It is perfectly fine if you want the PCV system intact, just know that even with a catch can you won't prevent 100% of the blowby vapors from going back into the motor. Also, make sure you have a check valve in place between the intake manifold port and the catch can, otherwise you will be pressurizing the catch can under boost. It's better to replace the PCV with the UPR Billet Hi Flow PCV Valve, and then add a check valve between the catch can and intake manifold.
