I discovered one more engineering failure about this "exclusive & high tech" OCC.

The outgoing hose from CV#2 is pointing upwards instead of pointing downwards. This will result in oil dripping back to the crankcase.
Trust me, I've tried it...

The stock PCV is designed for having a natural flow through the whole system and that is definitely something you should have in mind when you're designing a OCC.
The OCC it self should also be placed at the lowest spot in the system, just to keep the natural flow working 100%.
