what is a ccv mod

[tails101]

just wondering what CCV stands for and what is a ccv mod for a the 6.0

CCV is crank case ventilation.

basically your motor produces pressure through the crank case. it is expelled through the valvecover on drivers side on the diesels, and routed through a hose backinto the intake tube before the turbo. because you have oils and such in there, it cannot be legally expelled into the atmosphere.

a CCV mod takes the air and routes it down to the frame rail through a filter to remove the oil and other residue and then puts in back into the intake tube.

the reason for removing the oils and junk is to prolong the life of the intercooler boots, and to keep the intercooler, and the tubes and the intake and inside of the turbo cleaner and it also helps the boots from getting saturated and possibly slipping off and you having to replace them.

check out Raul@stealth automotive ad his CCV mod. its actually made and designed by fellow member and personal friend NCHornet. Hes on this site as well.

Thanks for the explanation...I have some wetness around the boots as well. Was curious if it was from the CC vent or turbo seals

Very well said Nick.



artsamm: If its oil, its more than likely coming from your CCV.

Thanks Nick,
Yes the oily boots is caused by the factory dumping the vent into the intake. There are several ways to do the ccv mod, but only one way that will meet emission laws. Not sure about it being illegal to dump it to atmosphere because Cummins has been doing it for years!! But it does stink and makes a mess on the ground and bottom of your truck. If you have any questions you can PM me directly.

ive had mine on for a while, no mess... but it does stink! and you can see the vapors at night

so say if you dont live an a emissions restricted state you could just run it through a filter and then dump it into the atmosphere and be ok or is there a reason it needs to go back into the intake
