Would this be possible on the CRD? Is this what you have to do if you don't install a Provent?

So if I install this provent and the dealer finds out will my warranty be toast? Sorry for all the question but this is my first diesel vehicle.

Thanks,

Wes

Not if it's installed properly, but if you have to have a definitive answer, ask the Mann Provent mfg or D/C.

Thanks for the info. I'll check with the DC but I think I could do an install, after reading this, that they would never know about. I would just remove the provent before taking it in for warranty work.

Yup and some like mine think it's a smart thing to do and would do the install for me.

You can do a stealth install, don't even have to remove the factory hose from the CCV valve cover vent to the intake piping.

I'm using something a little different from the Mann Provent. It's called a Condensator, www.condensator.com . Same idea, and about the same price as a Mann Provent. Used them on 2 of my gasoline vehicles with good results. Can't say anything regarding the increased mpg claims on their website, but they do one heckuva job trapping oil. One of the main differences from the Provent is that it uses 1/2" ID hose, a little easier to route, and a little easier to find fittings to adapt from the 3/4" factory CCV connections.

Basically, the thing looks like a remote mount oil filter, with a mounting head and a screw-on plastic collection jar. Inside the jar is a screw-on metal mesh filter cartridge. It has two layers of wire mesh with a layer of dessicant beads in between. Idea is you're creating a low-flow area inside the filter cartridge and jar, allowing the oil vapor to condense out in the filter cartridge and on the sides of the jar, dripping down into the bottom of the collection jar. There's also a small air bleed fitting that feeds into the filter cartridge if necessary, to introduce cooler air to help the oil condense out.

If you look at the top of the fender well with the hood raised, where the inner and outer panels are bolted together, in between the mounting bolts there's a gap between the two panels, just large enough that a piece of 1/16" thick aluminum will fit in snugly to a depth of 1 1/2".

That's how my mounting bracket works. It has a 1 1/2" long tab that slides into this gap, then a 1" drop to allow clearance for the hood gas strut, then takes a dogleg to clear the boost controller to where I have the Condensator mounted, behind the boost controller and outboard the coolant tank. Takes all of 10 seconds to install or remove it from the vehicle.

Hooking onto the CCV vent, I have a short piece of 3/4" hose and two screw-together hose fittings that make a 90 degree bend and adapt from 3/4" to 1/2" hose, such that it's pointing straight at the condensator and far enough out to give a straight run past the front of the coolant tank.

There's enough room under the noise cover that you can simply lay the factory CCV hose on top of new connection to the CCV vent. With two 90 degree hose/pipe thread fittings and a 90 degree pipe thread elbow, I made a 180 bend that brings the 1/2" connection to basically the same position as the connection for the other hose, a straight run past the coolant tank to the condensator, with the 3/4" end plugged into the factory CCV hose.

So when I need to take it to the dealer, I just undo two hose connections, slide the bracket and Condensator out of it's slot on the fender well, and plug the factory CCV hose back on the CCV vent. Takes all of about 5 minutes. Then to reinstall, I remove the factory hose from the vent, slide the condensator back in place, and plug the two hoses back in.

Wes,

Per the Magnuson Moss warranty act (search the forum for it - we discussed it already - or do a wider web search) the dealer would have to PROVE that the provent caused whatever problem the dealer is voiding your warranty for. They cannot simply void your warranty because they feel like it.

If it makes you feel better you could swap the original hose back in (only takes 10 minutes) but I won't be.

I've had to deal w/ motrorcycle dealers that have threatened to void warranties in the past due to modifications I've made for racing - I have no problem standing up to them and escalating to the regional folks if need be. As long as you go in knowing what you're talking about (make sure to say something like, Per the Magnuson Moss Warranty Act of 1975 you must prove that my modification was directly responsible for the failure of whatever part you brought it in for, blah, blah, blah) they'll grumble and just do the work.

Well, as soon as I can find the bloody software disk for my camcorder, I'll get the computer set up so I can download some pics. Old hard drive fried about a month ago, and haven't gotten around to setting up the new one so I can mess with the camcorder again. Been so long I've forgotten where that @#$%#@ disk is!

How do you tell when the filter needs changing? I was forced to run fossil diesel (no B-99 or B-100Was available) on a recent trip and now the filter is vary discolored.

You can tell by looking and it's a wire mesh filter that you can clean in some diesel fuel and reinstall if you are talking about the Condensator the Provent says just change at x number of miles. The Mann ProVent filter is about $25 retail and is anothher reason I didn't buy their filter system and designed my own for VW's which had a recleanable filter that was sold for $1 and lasted many thousands of miles.

Where did you buy your condensator CCV filter?

Their website is www.condensator.com. Website wasn't really set up for online ordering last time i checked. I wrote down their phone number, gave them a call, and ordered one over the phone.

they have the application info on the website, but basically you'll need a Model C for a diesel engine.

Prices on the website are in Canadian dollars, with the exchange rate it ends up being about the same cost as a Mann Provent.

Beauty thing is, these things also work wonders in the PCV line on gasoline engines.

Your link is wrong. Here is correct one. Condensator

Just noticed they do volume discounts, wonder if someone here has the resources to put a group buy togather.

Guys, might want to hold on a second before ordering a Condensator, based on the sizing by their website. Based on what I'm seeing on my CRD, I believe the Model C is too small to handle the airflow (too high velocity), and may have to go with a Model D.

The Model C I have was originally ordered last year and installed on an '04 Dakota I purchased in July last year. I removed it from the Dakota when i traded it in on the CRD back in Sept. When I checked the website, going by their sizing requirements for diesels, I figured I was good to go putting it in the CRD.

This past weekend, I replaced the heater hose I used to originally install it with clear nylabraid tubing. It had been installed for the last 800 miles I've put on the vehicle.

In the return line from the Condensator to the factory intake hose, approximately 18" long, there was gray sludge and oil at least halfway down the hose, and standing oil in the outlet nozzle of the condensator. The reason that there was visible oil only part way down the hose is probably because the "clean" section of hose was in close proximity to the coolant tank and the heat from the tank kept the oil vapor from condensing out in this part of the hose.

When I disassembled the unit itself, inside the jar there was a small amount of gray sludge on the bottom and about an ounce of water, the sides of the jar seeming to be noticeably clean. I looked inside the top of the mounting head, and there was oil and gunk splattered all over it. The mesh cartridge had a small amount of oil dripping off of it, and black gunk inside it.

When the mesh cartridge is screwed into the mounting head, the top of it is only 1/2" or so from the inside surface of the mounting head, and the outlet port. the cartridge itself is approximately 3" high and 2" in diameter. The hose connections on the mounting head are sized for 1/2" ID hose, with correspondingly sized passages inside the head.

Basically, I think that the CCV system has too high a flow rate for the size of the cartridge and passages in the Model C, the air is moving at too high a velocity to give the oil that's still in vapor form time to condense out insie the unit and is being carried over. I believe that what oil there was inside the filter cartridge and jar was what had already condensed out in the inlet hose prior to entering the unit and was just pushed along by the airflow.

I went to Autozone, and found a couple of fiber filter elements designed for an old style air breather filter, flat discs about 1/4" thick. I trimmed them to fit inside the mounting head and stacked both of them inside, then screwed the cartridge back on, so anything going out the outlet port would have to pass thru them. After two days of driving, you can see there is still oil vapor getting past them, a line of oil along the bottom of the nylabraid outlet hose to where it hooks into the factory CCV hose.

Looking at the Fleetguard website, they have an add-on CCV system that is designed to condense out the oil and drain it back to the sump. For the engine in the CRD, they say it would require one of their systems with the capacity to handle 5 1/2 scfm air flow. That's pretty healthy.

I talked tonight with the gentleman in Canada that owns the company that manufacturers these units. I described the above info to him, and he agreed with my airflow assessment, that for the size of the engine and this particular CCV setup, that a Model C would have been borderline to begin with. He's going to call me back in the morning, and we're going to discuss it further, including whether or not a Model D, being a taller unit, would fit in the same location.

The Model D apparently is sized for 5/8" ID hose and has passages sized accordingly, has a taller collection jar, and the mesh filter cartridge is two of the normal size cartridges joined together end-to-end, double the length.

I'm also going to ask whether having the hoses in proximity to the coolant tank might be having an effect, adding enough heat so that the oil vapor won't condense out inside the unit.

hi guys
follow this thread on the aussie board have fitted a provent to a 2003 diesel kj very impressed with the results pictures on the second page
after enquiring with Mann an d Hummell AUST there may be a smaller unit being released on the market in 2006.

hope this is helpfull

OK I'm ordering the Provent today. I'm going to try and do an install that looks as close to factory as possible. (I have a strange feeling that if I do it right the dealer won't know it's not suppose to be there on regular oil changes and stuff) I do most of my own service work anyway. I will try to take lots of pictures. I'm going to also remove the hoses from the intercooler and the intake just to document how much gunk is in them at 12000 miles.

OK ordered, now just got to get it and install it.

If anyone is interested in getting one, order it from Chris at Air Supply. Phone Number 1-714-379-5800. He seemed to know alot about the Provent and was able to get it shipped out same day.

I installed the Pro Vent @ 5,000 miles and now have 13,000. It collects alot of oil. While on a recent business trip I had a MIL come on. I went to the dealership in Missoula, MT. The code was for the MAF, but they said my air filter was pretty dirty so they replaced with one I had. (was going to do a service when I got home). Back on the road. 100 miles later MIL agian. Took it to the dealership in Post Falls, ID same code the air out let on the air filter box had a dent in it. Cleared code. Back on the road after a weeks worth of meetings, 100 miles later MIL agian. Took it to my dealer in Salmon, ID same Code. Ordered air box part and new MAF. Have now been installed. NO ONE at any dealership made mention of my Pro Vent other than to say what a good idea! All of the dealerships were GREAT.
