Bought a Vibrant venturi to have welded into my exhaust. I love the idea of the CCV mod that I currently run, but the kind of driving I do doesn't allow it to be properly scavenged all the time IMHO. Sitting in stop and go traffic in 90° weather isn't good for anyone, lol. I have read of a few people doing this with some success on a 6.0. Anyone on here done this?
If you do not get the entrance into the exhaust just right it will not pull a vacuum on the crankcase but create positive pressure from the exhaust entering it. That being said if you get it right it should work just fine.
Do it Chris. I was so tired of the smell and lingering smoke that it would huff in high heat and traffic.
I welded the Vibrant piece in a couple months back.
Works perfect.
At an idle, you can feel a slight suction at the hose tied into the CCV vent on the valve cover.
I think I got a little fancier than needed.
I found a 90*, silicone hose, with a 1" opening on one side, and 3/4" on the other.
I used a brass 3/4" to 5/8" hose barb reducer from the end of that hose, to your standard 5/8" Shields Marine fuel hose.
I ran that hose down the frame, across the front of the trans (with Ancor cushion clamps).
To connect to the Vibrant venturi I found a brass JIC fitting that threads on with a 5/8" push lock hose barb.
On first start up, I get a little haze (could be my nozzles too).
And after a long, heavy tow, around town in higher heats.
Daily driving, never even notice it.
Hello all! I have a simple question that I'm hoping has a simple answer, so here goes it! I'm gonna be doing a CCV mod here soon and was wondering if anyone out there has done this.....utilizing an in-line catch can, while routing the fumes from the out-side of the catch over and plumbed somewhere into the exhaust pipe so the fumes simply flow out the exhaust with the rest of the spent gasses. Doable? Foolish? Opinions are more than welcome and enthusiastically requested!!!! Thanks in advance everyone!!!
It's been discussed at length. IMHO, the main issue is to get the geometry of the nozzle inserted into the exhaust stream profiled correctly so that the varying and not-at-all-close-to-zero exhaust pressure doesn't cause the exhaust gases to push into the ccv or otherwise block flow out. It also can't be pulling like a shop vac. Other than that...
OK, next question....can the hose, coming from the engine, be reduced from 1" down to 1/2" or 3/4", at the can-going into the can and 1/2" out of the can back to the back, or does it have to stay 1" from the engine cover, into and out of the can, back to the back of the truck? I ask because I made the can cut forgot to double check the hose size out of the engine add made the can with a 3/4" hose fitting going into the can and a 1/2" fitting coming out to go to the back of the truck. Not a big deal if I have to remake it, but would rather not if I don't have to! All opinions matter!!!
If you drop down lower than about 7/8 on a 6.0 it'll make the engine leak from every gasket possible from the excessive pressure. Seen it on a 6.0 and on a 24 valve dodge. I'm pushing quite a bit of boost into my poor stock engine and i run my hose without a catch can and just drop it below the driver side rear door and I don't even notice it at all. Angle the hose down so it doesnt get your frame all oily and call it a day. A healthy motor won't be dripping oil from it for you to even know about it. Catch can is just a nuisance imo.
Someone came off that 3/4 hose stuffed a 1/2" hose in it and ran it to the back of the truck.
