I agree with you. The only reason for not having a road draft tube is for emissions

 

This sounds too easy. Whats the draw back? Fumes, smell oily drip? Any picts of this set up?

 

So, I shouldn't believe Mechanics that I talk to on a regular basis who say these things on this website?
The CCV is a huge controversy. Go talk about it in the SD forum, every one of them believes in running a hose to the rear bumper. If you even try to talk to them about pulling a vacuum with the exhaust, the same concept which was implemented poorly with the stock system, they will tell you how big of an idiot you are.

As for a compression test, I would run one if my truck was having problems, but it has none, except for needing a new steering box and new tires.

Common sense tells me to expand on the stock system and improve it.
A 300k mile diesel is going to have blow by. Period. Any mechanic on here will tell you that.

It's always possible, but considering my truck runs great, I'm not worried about it. I hate buying used for that purpose, cause you don't know how well things were taken care of before. As for just running a tube down the side, I'd rather try to not have my truck leaking another spot of oil on my driveway. Hpop has a small leak. Gotta love dime sized dots when you park.
I don't know if you checked your engine lately, but we have a vacuum pump on the drive-line for the whole reason that our engine does not pull a vacuum. The system they are using to pull a vacuum on the crank case is marginal at best.
I guess an engineer who worked on this system could never do anything wrong, ever.

Just look at what ford has done to other motors they have gotten from other people and tell me that again with a strait face and honest answer please.
I have another one sitting in my driveway right now that ford made worse by putting their parts in it. And these ones were NOT for emissions.

I honestly wish there was a way to make a road draft tube for our trucks. I'd rather run that then a rubber hose to nowhere.
I'm putting a catch can on it either way. It's better to not let that crap get all over the road, though with just naturally vented system, it shouldn't be pulling oil out to nowhere anymore and staying in the motor.


Now, anyways, Thanks for everyone not even trying to answer my question and telling me how horrible my stuff is.
I appreciate your suggestions, but.
I already knew them, Cept for the stuff powerstroke8994 posted on how many inches of water its supposed to pull.

 

that's the biggest issue with just dropping a tube by the motor, the crank case gases will make you choke really good.

The draft tubes pull a vacuum on the crank case while the vehicle is moving sucking gases out and leaving them in the wake of the truck.

The whole idea behind what I'm trying to do is use the stock system to burn off the excess gases, but still pull a proper vacuum on the crank case, which should increase motor efficiency, at least a tiny bit. More than venting to atmo will.


The main deal behind dropping the CCV system that is stock is that at some point, the motor will start pulling oil into the turbo. This in turn causes the dreaded intake boot rot, cause the boot is not made of oil resistant rubber. Which is why we buy silicone replacements, cause the stock system is a failure.

 

If i was you i would run it into a catch tube with a little breather on top with a filter instaled there too.

This is way over thought too. I work for navistar and the only reason the vent goes to the turbo is cause it bruns the oil vapor while keeping the engine clean on the outside. Its a sucking effect which make it a great place to put it. Emissions are much more strict on pickups which is why the medium dont have it. Blowby or the smopke coming out is only 1 thing and thats combustion gases passing by the rings an d into the oil pan and then upwards. The way you check it is to cap off your breather run the truck wide open at a stop and see what it is using the orfice tool which screws into your oil cap location. If its too high the enginehas worn rings and or clys. No 2 ways about it. I am not doggin you at all man but just stating facts as per training on the 444 and such. Navistar has always had poor CCV design until the release of the maxxfroce7 2010. The design was so bad on the 2007 to 2009 engine for buses and truck that it was sucking too much oil out and running truckoff and blowing up. Got 3 that are in now for that. Just put it into a can like i did on my 2002 and be done with it

 

No hate towards you man. You played the cards right. No hard feelings.

What you suggested is basically what I was going to do, but instead of a filter, just plumbing it back into the stock CCV location to still semi work like its supposed too.

But, pulling a vacuum is better, thats why I was asking about using a vacuum pump. I see on a few tuner sights guys are doing this on gassers and gassers with turbo's.
The only problem they post about is the vac pumps not keeping up when the turbo is spooled, so you need a blow by valve as well so the system doesn't cause compression.

I just get a good amusement by people answering totally unrelated things on here as to what I'm asking.
I appreciate your help though. I'd have checked it long ago if I had the tools to do it, but I don't. I know the truck runs good and doesn't burn oil. So blow by does not bother me, I'm not the only person here with blow by.
By the time it's ready to give me problems. I'll have enough engine rebuilt and ready to go.

 

I came up with a sweet fully serviceable catch can that cannot accidently "fall apart" for 10 dollars.

I used 5/8's fittings though. Guess the CCV kits use 3/4 hose. I might switch one out for 3/4's and Leave the breather at 5/8's.

I don't think i have the right size tap for a 3/4 inch barb fitting.

 

William I am not rippin on you man no need to be nasty this Idea of a catch can has been done before TJ has one on his truck why not ask him for some pics.

I think it is weird though that your getting that much oil I have used the ccv mod with no oil ever coming out the tube I have it hooked up stock now and have little to no oil in my turbo.

sorry to ruffle your feathers chum

 

see.. i bet if you come up with a hose that comes off the dog house, goes towards the fender a smidge then straight up and then into a 180° U turn then back down into the intake so the oil cannot come straight up but the stinky smell goes into the intake that would be golden. so basically making a design that mimicks going up and over the brake booster on a MUCH smaller scale.

 

I think if you got a link of hose, some clamps, and another elbow like on the doghouse that would be pretty easy. Maybe spin the doghouse 180*(howd you get the degree symbol) and add enough hose to go over the top of the intake tube and back under where the stock ccv setup ties in. Add the other elbow to the longer hose and voila, ccv vents into the intake still but surely no oil can get out now. I don't have my truck to look at and see if it's even possible but sounds alright.

 

I got mine venting to atmosphere and I have no oil dripping from it(shrug).

But if you want to pull a vacume, run a hose to your exhaust and drill a hole in it, put an oriface in the hole in your exhaust and weld it up, atach your vent. As your truck runs the exhaust gasses passing by the oriface working like a venturee(sp?), sorda what you find in carburators and it will draw your crankcase gases out of your engine. Just make sure you run the hose in a fashion that there is nolow spot that climbs back up otherwise you will have condinsation issues collecting in the hose in the colder months and freezing up.

This was an old racing trick that was told to me by an old timer.

 

Yup this is the way the ISX uses its egr system. Works well.

 

Yep use the exhause to pull a vacuum. A few sd guys have it run that way

 

Still in the end what's the big deal about just running a road draft tube? If you install a new ilter oil shoulnt leak outta it unlesss there's a large amount of blowby

 

Agreed, were making somthing bigger then what it is.
