My vote.....dump it into the atmosphere and be done with it. The crud I'm seeing in my catch can convinces me to not even try it filter it, it would never end and soon clog up by my mistake of not servicing it in time and then my crank case is under pressure....almost back to stock with more worries.
Yes…agree on all points…just wondering if there is any lube value to the turbo vanes from what ever survives the filters…..leaning towards open air. Truck runs and sounds better since rerouting the ccv to open air…..so this rancor could be turned into a catch can by pulling the filter and putting a roll of metal screen in place of the filter. Right now I think any liquids are no the 20ft line I have running to the bumper.

Which turbo vanes do you envision getting lubed from the oil in the CCV system?

I seem to recall seeing a video from Diesel Bob (I think that was his name, he passed away recently?), where he poo-poo's the open air approach, stating that the oil vapor lubricated the "turbo seal", of which I'm unsure what he was referring.
The vanes are in this generic variable geometry cut away in red.
Does ccv oil mist lube them….maybe
i do know it is a PIA to replace the turbo so I don’t want to create a new problem by solving an old one.
So how much lubrication do you think the oil from the CCV (or any place that goes through the combustion chamber) has after the combustion event?
I will say it has more of a sticky gooey properties than lube at the point it comes in contact with that side of the turbo.

so the oil everyone finds in the intercooler duct work and intake is not left over combustion products….its engine crank case oil that suspends in the air and is carried off thru the ccv vent.
the crud folks are seeing on one side of their throttle body valve and lower half intake mushroom is from the egr valve.
and you are assuming that catch cans capture 100% of the suspended oil ….which they don’t….what you are seeing in catch cans is due to the can case being cooler than the gases passing thru it

Correct me if I'm wrong, but wouldn't the vented oil from the CCV side get mixed with the soot from the EGR side, and then that would lead to the caking up of the crud? Both contaminants combined would appear to not be optimal for "lubricating" the turbo, IMO.
Seems like one would still like to prevent that soot from binding to the oil vapor, by either eliminating the oil vapor or the soot. However, as shown in those FASS filter threads and videos, the soot elimination approach is still experimental (and viability still to be determined).
The problem I see is if the OEM CCV boxes actually worked like they should, to collect the oil from the blow-by gases and let them drip back into the driver's side head, there wouldn't be any oil in the intake or mixing with the EGR gases to crud up the works...
Unfortunately, it's just "accepted" that there's oil in the intake from the CCV system... which IMO, the less the better...

For any oil to get from the intake (compressor side) of the system to the exhaust (turbine side) it must experience a combustion event BEFORE it gets to the parts you are referencing does it not?
Or is there another path it can go?
