K&N passenger valve cover filter for fresh air in the fill port.

All of your diagrams seem overly complicated. The stock systems are relatively simple and all you have to do is plumb your catch can before it goes to engine vacuum.

The driver's side valve cover is the fresh air inlet. It should get air AFTER the MAF.

The passenger side valve cover is the suction side. Plumb that to your catch can, then to the manifold.

If you have a port on the valley cover, plug the passenger side valve cover port. Run hose from valley port to catch can, then to manifold.

That's it...

You are burning unmetered air, assuming you have a MAF. The intake for you system should be in the intake tube after the MAF. If you are running an SD tune, never mind....

I have only seen check valves used in forced induction systems.
