CCV reroute issue

travisH3 · May 24, 2014

I did the CCV reroute and today I was down at the local track with friends and when towing my buddies truck back to shop(blown trans) there was a car parked behind me and a guy said I had an exhaust leak, well when you shine lights at my truck the haze from the ccv is pretty noticeable. Id rather not be sitting at a stop light and people thinking the wrong thing and my truck looking like somethings wrong. will plumbing this into the exhaust at a 45 degree angle help with the haze at night or will the haze just come out the tail pipe? which would be better anyways because it wont look like the truck is leaking something or smoking under the bed. thanks for the help fellas!

Mine is like that.

I'd rather be able to have mine in sight, so If it were to start dumping or show bad signs id notice.

A lot of people run them all the way to the back.

What we do on the 7.3s a lot is run it into thing thing mounted on the frame(link below) then run a line out the other side back to the intake.

mine is ran almost to the back tire. I would rather see it as well to make sure I know the line isnt pinched and what not.

I like that, only issue is now my no limit intake doesnt have a spot for CCV but I could always make one. I will ride it out and see what i thinks best. will a catch can get rid of the smoke you see at night?

I like that idea, I'll probably do the same thing when I get around to it

From what I heard the shorter the ccv the better

Mine is in the exhaust. The fitting is cut at a 45 and its angled in the ex at a 45. Id rather have it coming out the exhaust because I couldn't stand seeing the hazing coming from all around the truck and I didn't wanna smell it. Now you can't even tell it.

A catch can won't do anything for the blowby. I ran mine in front of my fuel tank, you could definitely see it through headlights or when it was warm outside, didn't really bother me though

The catch can is so you can return it back to the intake without putting the oil in there

Exactly. Just so it's not vented to atmosphere. I've been told putting it in the exhaust isn't good either as exhaust back pressure is greater than the ccv pressure.and pressure doesn't car about angles.

I see. I thought he literally just meant an oil catch can for the cvv

How much back pressure can be in say a 5 inch system after the dp? I would think it would work in a way to suck the gasses out of the crank case

Throw a gauge on it and find out.

Do a little research on the Bernoulli Principle.

It doesn't have anything to do with back pressure. It's all in having enough exhaust velocity to create an area of low pressure at your scavenger fitting. This area of low pressure works like a vacuum, pulling out the crank case gases. The higher the exhaust velocity, the more vacuum.

Didn't Wayne do some testing with this on the 6.4's?
