Air Line Oil Trap for PCV Line
Hello, I felt compelled to share this with you because you guys helped me so much diagnosing my engine vibe( which turned out to be the HB) even though I have a Grand Cherokee with the 5.9 and 46RE.
Well, I just got done with the plenum on my 360 and took a whole afternoon scouring the intake clean. I noticed I had some oil in the intake after I got it all back together and after checking for leak all over the place, I determined that it was coming from the PCV line into the intake. There was a small amount of oil right near that opening. I ended up putting a Husky airline filter inline with the PCV system to catch the oil that may blow-by in the vapor and keep the intake as clean as possible. I kept it at 3/8 opening because I did not want to impede the flow. You can get smaller filters but they use a smaller opening.
They also sell brackets for it. I have my rigged with zip ties until I can fab the bracket.
Here is the link with pictures. It's to a Jeep board I hope you don't mind http://www.jeepforum.com/forum/f13/p...h-can-1424223/

That looks awesome man! Whats weird is I've been contemplating doing this exact thing the last couple of days. I got my new JEGS catalog and they had some universal setups in there that gave me the same idea. Hope it works out good!

I don't know yet. I just put it on. I have probably only driven under ten miles with it so far. Another guy I talked to says he empties his once every 6 months. I would think it depends on how bad the blow by is though.
The Hemi guys have been doing this for quite a while...might not be a bad idea especially on a high mileage truck.

With a little more research, I came up with this concept also being known as a "catch can".
Here's some more detail on the concept.
And a video of one in use.
JEGS have an air oil separator for ~$45.
