Check my PCV setup please

Most definitely run it. Like Rusty says; if you run it back to the air cleaner, the oil will collect there instead of on the valve cover. Thing is; if your ring-seal is good, the breathers will collect the oil, and you can wash them out at intervals.Unfortunately that's a lot of work to do properly, and if not done properly can lead to other issues.

No, what I was saying is that air has to move both ways through those breathers. When the engine is working hard, it will be blowing crankcase pressure out the breathers. At all/most other conditions it will be drawing air in the breathers.
I have heard that some of those pesky breathers have one-way rubber flapper valves inside them.Guess which way they don't work.
It seems to me it would be more important to figure out where the oil is blowing out right now than to be re-designing your PCV supply/return air.
To that end I would prove the breathers are two-way, and then pressure test it.
