I've burned more money than I care to admit trying different combinations of catch cans, hoses, fittings. I'm going to guess $500 to date.

The "elephant hose mod" is the easiest solution if that is what you are trying to achieve.

I have that now, but relocated to a full inspection location. And it irritates me to sit at a light and have enough blow by wafting out from under the Jeep that I look vaguely like I'm on fire.. the latter of those two is incentive enough; the former makes it a time constrained requirement to address...

Edited after realizing I hadn't read all pages on this thread:

Everyone posting on this thread to date is obviously much better informed than I am, so please excuse my ignorance, but is the issue that this installation addresses related to the fumes I smell in my cabin when I cold start in the morning? For the most part, the fumes go away after a few minutes, but on my way down from a ski resort in a snowstorm last weekend (starting at 10,000 ft), they were much worse.

A few things that might or might not be related:
1. I have an oily film accumulating where indicted here.
2. About 18 months ago I addressed the swirl motor issue with the large modified hose (presumably what is referred to as the elephant hose with the red nozzle) that redirects oily airflow so it doesn't gum up the swirl valve motor.
3. Recently replaced the glow plug control module and all glow plugs, having gone for quite a while with some very rough starts.
4. I also recently replaced the shifter module, but it seems very unlikely that's related.

Thanks for any suggestions any of you may have, or feel free to redirect me to a less technical thread where I can get an education : )

Edit: didn't read all the way, and see that you had a diesel.

@Nicksut- The fumes are definitely from your elephant hose modification. You may also have a leak from another hose in the area you indicated. Do some digging and determine where the oil is coming from. Always suspect anything that has been recently worked on, moved or modified when looking for problems.

How about expanding the Air-Oil Separator search? There are soooo many companies that think they have this problem figured out.

It sounds like the Canadians need a water heated AOS like this Crawford unit:

This company offers custom port sizes/locations (but not water heated):

I have a Moroso AOS in my VW and it does a HORRIBLE job at what it claims to do. These jerks charge > $150 for such a piece a junk. And the funny thing is: the design is the same as the Billet Technology POS. Why are you guys buying this unit anyways? It's just an easily CNC'd hunk of aluminum.

It can't be that hard to get this right. I'm actually thinking about sticking my elephant hose's "trunk" into the air box snorkel. Maybe just clean the box out once in a while. Or just let it drain to the ground.....

If that doesn't work I'll look into an AOS or exit to exhaust.

Hate to revive an old thread here, but I gather from reading this that the Billet Technologies catch can is not viable for a CRD due to hose connector fittings having too small of an ID to allow the necessary venting? Too much backpressure on the CCV?
