So any kits available for the gt4?. I would think we would have one available because of our DFI engines.

I may build my own, is there 1 or 2 pcv’s in our cars?

thanks in advance

 

There are no pcv's in the GT4. There is a vent line from the top of both cam covers that connect to the air/oil separator. The aos is then connected to a port on the intake plenum inboard of the throttle body.

I plumbed a Radium catch can to the output side of the aos. The catch can oulput connects to the port on the plenum.

I drain 1/2 to 3/4 oz of fuel smelling oil fluid from the catch can after every 2 day track event on my Clubsport.

 

I used to have a catch can but removed it, see link in signature.
Compared to someone else that didn't have one, we both had the same amount of oily residue around the intake valves.
So most or all deposits were from oil escaping from around the valve guides.

 

So, if there’s no check valve(s) then this system is considered an “open” system, and only missing a process to collect the oil, and vent the mist. Am I correct in assuming this?

Edit*
after more investigation, I’m reading the OEM AOS, has a one way check valve. So it’s a closed system.
