I'm going to be doing a CCV mod on my '08 F-350 after I figure out which kit I want. The next question is should I tie it into the exhaust, use a catch can or let it vent into the atmosphere? What are most of you guys doing for those of you guys that have done this mod? What are the advantages and disadvantages between each other? I like the idea of tying into the exhaust with a 45 degree bung but afraid that it will add back pressure and where at on your exhaust pipe do you weld the bung to? What are your guys thought on this and Thank You!
CCV mod, tie into exhaust, catch can or atmoshere?

Disadvantage of atmosphere......SMELL!!! Just something to get used to but I would do the 45 degree into the exhaust

Mines routed to the exhaust. No side effects so far so that's what is recommend

Only thing I had to change on my dark horse kit was where the hose connect to the oil fill can. With the tow x turbos the fitting was hitting the turbo so I had to cut it off and reglue the fitting.

Do you see any haze out the tailpipe with it routed to the exhaust?

I so dont understand everyone complaining about the smell from the ccv. You drive a diesel, get over it, or dont do it! Imo, the smell was not noticable dumped under truck before fuel tank on my f250, nor can I smell it dumped near the cv axle on my tdi jetta...and i really dont think it smells bad at all.

i have a light haze. but i think its from the 30% nozzles i have. the ccv could cause a little too i guess. nothing really noticeable

Some trucks haze pretty badly, especially after towing. It would be nice to dump that out the exhaust instead.

My 7.3 had a steady haze when hot outside, didnt bother me a bit

your tough.
yes i drive a diesel and yes i don't mind exhaust smell. i still don't like the smell of hot oil and clouds wafting up beside the truck.
Theres been dozens of threads on running ccv to exhaust in turbo applications. The consensus was that the excessive air pressure of exhaust passing by the outlet tube could push the ccv flow back to the engine and pressurizing the crankcase. Is the 6.7 different from the 7.3, or has someone been able to figure this out the proper position of the ccv tube in the exhaust pipe?
I hate the smell really only noticeable at drivethru windows but it's there and putrid.
I would like a bung made for the exhaust so i don't have to buy an entire kit.
Can someone make a bung we could have welded ?
I may re-route mine across to the passenger side instead of against the fuel tank.
Never had a drip out of it to date and can't see any accumulation in the clear tube in the engine compartment making a catch can worthless.

Wasnt trying to be "tough" lol, I do hope you got my point though, and why dont you guys who dont like the smell run it to like the back bumper or something? I seriously dount it could be smelled being that far back
i think wayne pretty much nailed the install on his truck i think,
there really shouldnt be pressure in the exhaust anyway
I was going to try a set up with a map sensor in the crank case, test before and after but i have far too manythings going on right now to really concentrate on it anyway.
The exhaust thing would be nice because it will dillute it with exhaust gas as well as be hotter to help sort of burn it before it goes out the tail pipe.

I cant see why you couldn't get a piece of suitable diameter pipe, cut in at a 45 degree angle and have it done at a welding shop. I think I will try this. Just gotta figure out how which part of the exhaust to install it into.
