I do think a rise in the hose helps with drainback and that is how I did mine, but on mine at least there is still a lot of stuff being vented. I believe someone called it active rustproofing. :wink:

I think if you give it time you'll see the same thing.

Making a CCV filter for this rig is rather simple thing if a lathe was out in my garage, but other wise will just have to wait till I find someone that will follow my design idea.

In the meantime my filter material is working like a charm on the EHM, will post results Sunday or Monday.

Old Navy, I have a Lathe and Mill in the garage and will follow what you want to do. Email me or call 404-805-8302.

This project isn't dead yet. Stay tuned.

Amen brother, looking forward to seeing first prototype.

For members here just wondering, this will be more like the ones I did for the VW TDI a couple of years ago.

Good to know, I just wish I still worked at the machine shop that way I might have been able to pitch in as well. Keep us updated!

At a little over 10,000 miles, I installed my EHM today as an interim step to assess my CCV oil flow and possibly go the Provent route. Thanks, OldNavy, for your install instructions and photos...

I first routed the tubing over toward the drivers side then downward, so that my improvised "catch can" bottle could do its work. On the test drive afterward with the vent fan on full speed, I noticed that I could smell exhaust in the passenger compartment.

My theory is that on a moderately colder day like today (45 degrees), the exhaust must be rising quickly then moving along the bottom of the hood toward the passenger compartment vent intakes. After the test drive, I re-routed the EHM tubing up front behind the driver-side headlight. Now, the exhaust smell has mostly seemed to go away, though I still get a hint when idling for a time.

Has anyone else experienced this? Should I be concerned about breathing exhaust fumes due to this mod?

Mine is up and over the top and the Coke bottle is resting on the frame rail and we have never seen smoke or smelled anything through the heat or vent system. I have heard other on ocassions mention this problem, but we have never had it happen to us. I am starting to wonder why, have some of you done something different that has caused it or is it just a fluke???

Mine was routed down the driver side and vented way low into the driver side wheel well. I got fumes in the window and in the fresh air intake quite frequently when idling. I finally yanked it when I went in for F37 and I'm just going to leave it off.

The best way to vent this thing would be to weld a boss in the exhaust system and run the hose into the exhaust...

You would need a check valve to prevent a back flow and the penetration into the exhaust would need to be set up for an eductor effect to enhance the flow of the crankcase vapors into the exhaust line. JMNSHO.

I will go along with marauder on that, seen it tried on a TDI without success.

Not really... Just put the pipe in at a angle toward the rear of the talepipe and it will suck the fumes outof the EHM.

Yes really. That is what I said in engineering vernacular. If you don't place the tube to create a low pressure area where it is in the exhaust pipe it won't work.

I wonder if you could get this to work right after the cat converter right at the end of where the pipe necks down a bit.. or would the muffler cause too much of a restriction and backup the system? (a glasspack probably wouldnt hurt anything)

This is the venturi effect right?. I suppose you could put a sensitve vacuum gauge on the contraption and make sure it has a slight vacuum under all conditions.

oldnavy · **Posted:** Tue Jan 09, 2007 5:40 pm

The only way the TDI guys got it to work was straight pipe with no restrictions, it smoke a lot from the oil burning in the tailpipe and made a big mess.

Well, I will wait to see if your gizmo works out this time oldnavy.

Hi all,

Tomorrow we set off on a 3000 mile round-trip from PA to TX (1500 miles down in the next two days, 1500 back in a couple weeks). Since we recently had our turbocharger replaced due to excessive oil in the intake, I put a last-minute EHM into the CRD tonight. I unrolled two steel wool pads and stuffed them into a plastic soda bottle with a long screwdriver. I drilled the vent holes near the bottom of the bottle to force the vapor to travel through most of the steel wool. To attach the bottle to the 3/4" vinyl line, I used a 3/4" barb-to-barb adapter. One end of the barb is clamped to the vinyl line. For the other barb end, I used a heat gun to soften the plastic bottle top, put the barb in the bottle top, then tightened down another hose clamp to mold the softened bottle top onto the barb. Once this cooled, it was very secure. I didn't have anything handy to plug the factory line to the intake, so I cut a small piece off a scrap 3/4" wooden dowel (about 1.5" long) and put an inch of it into the intake line.

see pictures here

For those looking to do this, you'll want three feet of 3/4" vinyl hose. I bought four feet and had a foot more than I needed.

One thing's for sure - I'm looking forward to putting a much better CCV filtration system in this thing when I get back.

I forgot to mention an installation hint. The non-braided 3/4" tubing I bought from Lowes came from the last bit on the roll, and it was crushed flat with some kinks here and there, and a strong tendency to coil back up. I set our electric oven to "warm" and put the tubing in there for about ten minutes. Once warmed up, it returned back to its manufactured memory, and opened up completely round and kink-free and ready to install.

I also had the flattened end of roll tube. I got 5' of it and routed it
down the passenger side - straight down, and snuggled it into that
perfectly sized hole in the frame - I cut maybe 6" off it so you only
need about 4' - 4 1/2 '. I smell nothing. And it popped back to round
after heat from the engine compartment got to it.
I got this routing pattern idea from Eurekaboy, but he used a copper
downpipe. http://liberty.eurekaboy.com/ehm.htm

msilbernagel · **Posted:** Mon Jun 09, 2008 3:11 pm

You know...

An ideal solution might be to put a one-way valve in the tube and tap into the exhaust just before the CAT converter... that way, the cat could do it's job and burn off the hydrocarbon and also effectively deal with the smoke/smell.

The exhaust system is pretty free-flow, so I'd expect crankcase pressure to be sufficient to drive the stuff out and into the CAT.

Just a thought.
