Under most of your driving conditions, the breather will allow the PCV to pull air IN to the engine. All of that vapor gets sucked through the PCV, into the intake manifold and burned. When you're WFO and the PCV can't keep up, it might let some vapor out but for the most part, the breather is an intake.
In fact, for tits and shiggles, I tested mine and the PCV would suck a piece of paper down onto the breather port at idle.

Here, watch this video. I6 engines have some really funky wave reflection on the intake side. That's why I keep questioning the PCV being located over the "secondary" i.e. inactive side of the carb. I also believe that's the cause of the oily film all over the carb.
The guys on the Dodge Daytona Fourm in Allpar used this as a secondary evac system.
However it didn't look like yours. It was a 6" long piece of tubing inserted into a hole drilled then egged out into the exhaust pipe then making sure the pipe lays flat wield it into place.
It created a better eductor effect because the exhaust blowing by the open pipe inside the exhaust pulled more air with it. I haven't herd them complain of it not being effective.
I never tried it........so I have no first hand experience. But pictures and what knot.......
Here is a picture of what I think you have Shawn. From the inside of coarse. If it had a 90 degree fitting on it with the opening pointed down stream it would be similar to what the Daytona guys were doing with a piece of pipe........
You know, my '63 Chevy had a crank case vent system. even back then they knew it was important to get rid of the fumes in the crank case forcefully. It was just a road draft tube but it worked and you changed your oil every month.
My PCV system has no effect on my engine I could tell. no reason you can't get your to work. I think they gave you the wrong one or a bad one personally.
Yes, one side pulls the fresh air in, should be filtered.
Went to the garage last night to try a few things out.
Started the jeep and it would not pick a steady RPM.
It fluctuated about 100-120 RPM.
Pretty sure that indicates a vacuum leak.
But I couldn't find it for the life of me.
Fogged the whole thing with carburetor cleaner and couldn't find anything.
re-torqued the manifold bolts. got a hair out of a few of them, but no improvement in idle...
Idle was great up until now.
How does this crap just 'pop up'?
