Somewhere between Provent and Elephant Hose Mod

Well....after researching, I'll eventually pull the trigger on the Provent...but I'm poor right now.

So I modified Old Navy's Coke bottle EHM mod. I used a 20oz bottle. I drilled the same holes, but instead of using 1" tubing over the mouth of the bottle, I used 3/4" outside diameter tubing extending into the bottle about half way. This allows the gunk to blow out below the holes. I put some steel wool in the bottom of the bottle.

I tucked the bottle away over by the fuel filter where I can easily see it.

The good news is, when I pulled off the CCV hose, it was clean inside. I stuck my finger down into it and only got a small amount of spooge out of it. That's promising.

First day of driving with the Coke bottle EHM, and I'm happy to report that the Coke bottle has very little of anything in it. It's pretty clean. A little "mist" in it, and what looks to be water vapor that comes out of it, but not much nasty crap.

So far, so good...

so do you have an update for us yet?

I just did the EHM last night... something that i prob missed or it never got posted:

with this EHM, I'm assuming that all if not most of the engine covers are to be gathering dust on the workbench? i know they look like they serve little purpose but that's a lot of plastic under the hood if its just for looks. anyone had a EHM melt? or how about the wire harness that sits on top? My concern is mainly due to this mod taking shape during the "cool' months, its only a matter of time that we down here in TX will be pushing 100+ deg days... any thoughts on this?

And BTW... i am one of the few that has a lot of smoke comming from mine.

I put my engine cover back on. I don't think it will cause anything to overheat.

My Coke bottle EHM mod is working great. Still very little goo in it. The only downside is when I stop, I can see smoke coming out from under my hood. I'm not a big fan of the ghetto sled whooptie theme, so I just bit the bullet and ordered a Provent. I still don't like the idea of this junk getting sucked into the intake, but it's got to be better than the car next to me with the windows down getting filled up with smoke.

LOL!

As long as the smoke is dry, it shouldn't gum up the intake. Might cost me a bit of power and efficiency, but I most likely won't notice since I don't drive around at WOT much.

i put my main cover back on as well, so I'll post if anything happens...

one more thing, with the hose that you pull off of the CCV and zip tie up by the overflow, i cut a t-shirt to cover the top of that then zip tied it as well. the thought of having an open hose post air filter was kind of counterproductive as "dirty" air could get in to the intake this way.

I plugged it with a piece of 1/2" pipe and a cap.

does the CCV need back pressure er somthing? personaly i could care less if the oil and water end up on the ground and not in my engine. can you just run the CCV output to the ground and be done w/ it?

The CCV does not need backpressure, backpressure would be a bad thing actually. Yes you can run it to the ground, mine goes into the passengers side frame rail.

Now on to this bypass filter you have in you sig....have you got a thread on that already?

I don't mind the dripping on the road, just don't want it in my driveway.

I had one more thought as i was checking my coke bottle last night...

try to follow me here... the CCV hose goes into the air intake POST filter but PRE turbo.
the turbo works by SUCKING in air and COMPRESSING it.

Meaning.. we are correct in saying that there is no Backpress on the ccv but waht about -pressure???
does the ccv "puch" out the goo and smoke? OR does the turbo, help "PULL" the stuff out or is it both?? Or does it even matter??

i took my "plug" off of my ccv hose (the one i took off of the ccv" plugged it with my finger then had my son step on the gas, and could feel it sucking my finger.. (minds out of the gutter..think about your jeep in the mud insted! its still dirty!)

like i said it was just a thought...

Jeger · **Posted:** Wed May 02, 2007 11:23 am

The turbo does pull air through the CCV system, which would be fine if that air wasnt full of oil vapors and moisture, and if it didnt dump it right into the intake system. By just running an open vent, without the turbo pulling on it, you will probably have less volume coming out of the CCV. Its not important how much gunk comes out of the vent though, the important part is that it is not going into the intake.

skywarn · **Posted:** Wed May 02, 2007 12:22 pm

work with me on this one...

if it doesnt matter how much comes out then why not just plug it and do away with the whole EHM?

OR does it NEED to be pulled out by a vac. such as the turbo or as said before creating a vac by using the muffler or exhaust pipe, but not dumped into the intake. (that part i fully understand)

im just thinking out loud here... nothing more...

Jeger · **Posted:** Wed May 02, 2007 1:06 pm

You cant just plug it because it does need to vent. Otherwise you will build up pressure in the crankcase and start blowing seals.

Does anyone have a pic of where my CCV routes back into intake so i can snip snip this bish and let it belch onto ground?

off topic but answerd:

um i do somwhere on kj country but when i posted my pics on myspace no one but me could see them, still kinda new to this posting pics deal.

Heres the scoop, CRD has like zippo room in to mount the thing so that was the biggest challenge
it currently sits between the battery and the firewall. or more specificly between the battery and the ESP device.
i had to unbolt the battery holder and move an electical cable harness under the battery holder vs over it to make room for bypass unit
the bypass currenly sits there surrounded by high temp foam. My multi-meter read 170F for temp (engine temp)
I had a oil press gauge on it for a week or so b4 my 12$ oil press gauge broke, it read 30-70psi depending on conditions
I have plans on making a metal bracket to hold it in place better in the future but currently dont have it done.
I want to do an oil sample at 1000 miles to make sure im not getting excessive engine wear or anything funny going on.

Im using AMSOIL Synthetic 5W-40 Premium Diesel Oil (DEO)
https://www.amsoil.com/storefront/deo.aspx

i wanted to use the 5w30 series3000 i think its called but since i have an extended warentee on the vehicle, i want not to deviate from factory recomendations too much.
I am keeping extensive paperwork and measurements on my work to avoid warentee disuputes w/ my warentee company.

Well, I gave up and did the ProVent 200 install tonight.

My Provent arrived today, and I'd already done some research as to what was needed for the install. There was one thing I decided to do differently. Instead of using 1" to 3/4" reducers, I just slipped on 1" hose, and slipped the 3/4" hose inside of it. Seemed simpler to me and I didn't have to wait for glue to dry. I'm a KISS sort of guy.

I ran the 1/2" drain tube down to the bottom of the wheel well where I zip tied it to a bolt to keep it off the exhaust. It is sitting about 3" away from it, so I don't think it will get too hot. I put a small valve on the tube so I can drain it when I change my oil.

Pictures are worth 1000 words:

Chad's diagram with the PVC setup is very similar to something which i created for an old audi 4000 I used to own. it had so much blowby that it would suck oil from the valve cover into the CCV and totally saturate the air filter. I took an old 1 quart oil container and filled it with choreboys. I then clamped the 1 inch CCV hose onto the spout and inverted it on top of the motor and used a plastic tie to tie it to a bracket so it wouldn't fall over. into the bottom of the container ( now the top ) I inserted a half inch elephant hose, which I then routed down to the bottom of the frame. during operation the choreboys would condense the vapor and it would collect on the bottom of the oil can. After shutting down the engine the condensed oil would flow back through the CCV (I don't know why it is called a valve since it is not a one way flow). there was a lot of smoke that came from the blowby, but after passing through the condenser can there was no discernible smoke from the elephant hose. in our case with the CRD there is no room on top of the engine so any condensate can not flow back into the CCV but I like the drain idea of Chad's. also my CRD has very little blowby and no wet oil with it so I doubt that there would be much if any liquid condensate anyway. there is no need for the turbo to suck CCV gases out of the engine, There are only two purposes for the CCV #1 prevent blown out seals, and #2 vent moisture from the combustion blowby.

I routed my CCV hose "uphill" so most of what spews out would flow back down into the CCV.

When I was running the Coke bottle mod, it had a little gunk in it. Very little. It wasn't wet so much as it was gooey. Very sticky in fact. Not stuff you'd want in your intake.

My fear is that this stuff won't drain out of the drain tube very well.

Im having trouble following the routing in the pictures.
=========
What is the black round do-hicky on the top of the engine? looks like where it feeds back to the intake manifold? Thats odd b/c thats the pressurized side of the turbo and i thought CCV gunk would route low press side of turbo.

Where do the hoses from that black round do-hicky going over there by the air box.....

=========

So im thinking... CCV is comming from the top of engine (which seems weird too) and runs ovr to the air box some place (low press side of turbo but makse sense on that end).

=========

Either way im confused please help =)

Thats the CCV and the hose that goes to the air box is the one you pull and plug.

(i cant see the pics for some reason... but there use to be a sticky on how to do the EHM but now its gone...could we get Old Navy's Soup post back?)

The disk on top of the engine is the CCV. The hose connected to it is routed to the intake on the ProVent. I then connected a hose to the output of the provent and tied it back into the stock hose going to the turbo. Nothing is connected to the airbox. All the emissions from the CCV go into the intake UNFILTERED! That's why it's so nasty. The provent is a filter and seperator.

While it might be better, efficiency and power wise, to simply let the vapors vent to the atmosphere, I found that doing that created lots of "smoke" (probably just steam). It looked like I had something wrong with my vehicle when I was sitting at a stop. Sort of embarrasing.

The ProVent filters all the "wet" gunk that comes out of the CCV and lets the gasses pass back into the intake where they are burned during combustion.
