So I decided to plumb a "catch can" into the PCV of my car. I used a filter designed for an air compressor, I've used it for about a year now and seems to work ok. Catches about tablespoon of oil every 120 miles. I went for this small size due to the limited space in the TT engine bay. I did check the lower manifold and noticed some oil film still, so my setup is not keeping the manifold completely dry. I put a piece of steel wool in the bottom of the filter to act as a place for the oil to condense.
Thought I'd share a couple photos of it installed.
1993 Dodge Stealth R/T twin turbo, pearl white exterior (W29), red leather interior, W5MG1 transaxle, built 2nd week of August 1992.
lol talk about a blast from the past... I used to run two of those 10+ years ago, but I still occasionally put them together for others when space is limited.
FYI, the larger version also works with the capacity to hold more crap. We once had an ethanol-fueled VR-4 check after maybe 2-3 OCI's, and it smelled like a fermented alcoholic beverage lmao - super potent!

I also had success with a small filter there (but between head and intake not PCV), you can see mine in this pic from ~2007
funny! I used that same filter as a "catch can" on my Dodge Durango with a 5.9L engine, it worked fine but it's sealed so you have to throw it out when to much oil accumulates, so i didn't want to use it this time around.
