... That highest high of knowledge which marks you a true enthusiast of mechanical engine performance: is cleanliness, and it starts inside the crankcase as a vacuum which keeps the engine's seals and baffles clear of oil.

I'm totally in for cleanliness of air passage from the air filter to the throttle body and appreciate your passion and persistence.
I also agree that all these huge shiny catch cans and meters of hoses connected to them change volumes and pressures in PCV system which might actually change things for worse.
I still want to prevent having oily deposits before throttle plate and was considering replacing "that black can" with slightly smaller can to keep volumes similar to stock. And, ...
there is a restrictor in the hose connected to that "T" on valve cover to regulate the flow and pressures I assume. I think that removing it and adding small catch can between "T" and intake pipe will help keep things more clean. The only problem and question is how to keep that catch can accurately restrictive for healthy engine?
So, instead of that small filters that vents to atmosphere a good designed catch can should have means to monitor pressure and vacum, and to adjust baffling accordingly.
Am I right, or should we just keep all system stock and let intercooler collect all oil vapors like in VW and Audis lol.
