Well, considering that a PCV system's design and function is to evacuate crankcase fumes, and recycle them back into the intake system to prevent them from being vented into the atmosphere, it does what it is supposed to do.
Now here is the thing about catch cans. Why do you see water and oil being collected? Because the added length of hose, and the vortex created in the device cool and condense the vapors. By design. When you lengthen the distance between the crankcase exhaust port, to the intake, yes you will cool the vapors and they will condense. Some smart Snakeoil cookie figure this out and found that by doing so, can sell these things by telling people, Look how much goes into your intake!
DUH, thats what it is supposed to do, however, with the engineered design of the PVC system, the vapors are hot, and will not condense, but be combusted in the cylinders instead.

Spliced my Jeg's unit into the stock Ford hose, which didn't change the path of the vapors. So what shows up in the filter is what would go into the intake.

I didn't know those catch cans cost so much. Honestly, I thought is was a bad deal when I assumed it was a $40 product.
This 'technology' has been around for many, many years. It's an air compressor air/water/oil separator. You can get something similar from Lowes or Home Depot for $8-15. I think these guys just try to make it look a bit different so folks don't realize they are paying waaaaay too much money.

Unless it's a catalytic reaction (it isn't, it's straight combustion), actual real world impact of the oil vapor in the intake system is non-existent.
Di Hydrogen oxide is deadly poison....
