Could do something like this: Welcome to guzzle's CCV mod web page or do a filtered catch can with a return line to the intake.

 

I would think that the exhaust would make some back pressure, i did the same mod myself and i am happy with it, i dont notice much vapor and only get a whiff of it once in a while. i kinda like the smell anyway lol.

 

The "t444e" (internationals medium truck version of the 7.3) had the crank case just vented to the atmosphere. Just leave it like it is and drive your truck. If the smell of ccv bothers you, well, I dont think you belong driving a diesel in the first place

 

And you could always run the ccv hose to the back of the truck. I had mine near the fuel tank, and literally never smelled it unless I got out and stood by the bed

 

Well.. The truck has 240k on it, and I've only personally put about 5-6k on it since I bought it. Anyways, it does have a small amount of blow by, not enough to blow an upside down oil cap off when laying on top of oil fill. But.. It does always have a smoke cloud around it when running just enough that it looks as though it's a pile of crap that has the small amount of smoke coming between the gaps of the fender and the hood. So... It's more than just "I don't like the smell" but I take pride in my truck and prefer that it doesn't look like a pile of crap and the smell isn't pleasing. I don't care how awesome your truck looks or powerful it is.. If it has a smelly smoke cloud around it im not going to be as impressed with it

 

I'm with nomorescooby, I did that mod years ago and I had low miles, but in traffic at night you could see the ccv gasses and smoke in the headlights of the vehicle behind you, and it smelled like crap.

I got a deal on a racor 4500. It's to big to go under hood so it is on the frame rail. The ccv return goes back to the stock position on the intake. I just have to drain the can at every oil change, gets about 1/8 full. I beleive the model 3500 will fit under hood and then the can would be able to gravity feed back into the crankcase.

 

had a question about this crank case ventilation issue. know this is an older thread but here goes.

Instead of putting tube from top of valve cover under truck out back instead of into the intake hose, how about putting a hose into side of filter housing..

that way you don't crud up turbo blades with raw oilish stuff and you don't have to worry about the smell around truck when running some have mentioned after doing this mod.

I remember a truck that had the PVC hose go into a fiberglass filter type thing that was installed in bottom of filter housing on far end, away from intake horn area under the filter. It was made to be replaced when you replace air filter or at least you check it and replace as needed.

does that sound like a good? way to do this mod.

just spitballing here. oke:

 

If you ran it into the filter you would demolish your filter with that oilish crud in no time at all. I made my own ccv can out of some pvc fittings coat me like 6 bucks total and it's under the hood and feeds off the dog house into the can and back to the intake tube. I drain it every oil change and it works very well. I couldn't get myself to spend that kind of money there asking for those kits when with a little weekend time and a little work the same thing can be had for under 10 bucks. I can send you a couple pics of my ccv can if your interested

 

This is the one I made before I got a Raycor for free. Easy to do and mine never smoked.

 

Awesome, what material did you use inside for the filtering?

 

Stainless steel kitchen scrubbers. Some guys use plastic ones but not all plastics stand up to hot oil fumes.

 

Sweet, yeah the raycor looked like around $250.
Nice idea!
