Well that type of can is designed to completely replace the pcv system which can lead to higher crankcase pressures. To fit it the way that can is designed run both rocker cover fittings to the catch can and block off the fitting at the inlet manifold and also the one at the turbo inlet pipe.

IMO it is not an ideal system but you dont really have a choice when using that can.

Just remove the filter & Block it where it came off with a cap.

Run the hose from the PCV valve to the can, then from the can to just before the

turbo intake.

the factory setup draws in oil fume anyway so its not going to be any different.

You can make it better by if possible run a foam filter inside the can so it traps

as much oil as possible from returning to the intake.

the tyre of catch can I have has a removeable top so I can do this.

It would be a better option to purchase a non atmo type can.

the whole idea is to remove crankcase pressure with less oil contamination as possible

while keeping it legal.
