ccv question.

[Dietoremain]

i think this is a load of crap but this highly educated mechanic buddy of mine said i need my crankcase vented back into the intake because if not the engine will build up acid and destroy itself with contaminents... the only thing i see the ccv doing is reburning dirty air into the combustion chamber, my vapors can escape and not be trapped inside the engine, thats all i see that matters. it makes no sense to me, he said something about the blow by too.
arent alot of diesels vented to atmosphere anyway from the factory before all this emissions crap?

i just nodded my head and said 'uh huh' to him.
btw hes a gasser mechanic not nearly a diesel one..

wow, build up acid and kill itself........

[HVAC SuperTech]

yeah, thats retarded. acid build up? NO. and the older diesels arent vented to the atmospher, not that i know. the purpose of the CCV mod is to remove the oil from the air from the crank case, and return it to the intake as clean oil free air. if you keep it on the intake directly from the valve cover, you let that oily residue build up inside your intercooler piping, boots and intercooler. once the boots get saturated with oil, they breakdown and can slip off the intercooler piping and cause boost leaks. or they just breakdown and cause boost leaks.

Raul at stealth automotive sells a member deigned kit. Its called NCHORNET CCV mod. I have it on my truck. SEVERAL SEVERAL other members have it on their truck and it works fine.

I would suggest getting one.

PS: to all nay sayers of the CCV mod, dont let this turn into another thread like the last one. YOU WILL GET A VACATION FROM THE SITE!

[no-tel-in]

that sounds like a load of sh!t... The ccv mod is fine, tons of people run it!

[Dietoremain]

yeah i think he was bs'ing cuz hes a tree hugger or totallyy confused and thinks i said i blocked off the vent or something?? if i did that i'd have oil leaks everywhere lol.
thanx i just wanted to know if anyone else heard anything ridiculous as this.
I currently vent to atmosphere, just took it off and ran a hose down on my frame behind the front left tire, but ya i'll probably get the kit eventually.

It was my understanding that Ford had Navistar put in the elbow from the 'doghouse' back to the intake tube to meet emissions (or w/e) as the original Navistar T444E engines used in the International (big) trucks were vented to atmosphere.....

[NCHornet]

That is a bunch of BS!!! FWIW Cummins has vented to atmosphere for years, yes many or the OTR trucks do as well, that is why they are coated with oil under the trucks!! I don't recommend doing it and it won't be emissions compliant, and trust me it's coming. If anyone has ? on my mod you can email me at

Yes, please don't let this turn into what the last thread did!!!

NCH out

[BuickLeSabre1960]

don't mean to go against the grain but if it is not properly vented it will build up excess acid in the oil. The pcv system isn't necessarily a government pushed EPA thing, it is so the excess hydrocarbons that make it past the rings don't build up in the oil.

With that said there is a proper way to vent it to the atmosphere, but there is a reason the automakers went away from it and to the PCV system in the 60's. My '60 was one of the later cars to use the downdraft system, and you can tell when I pull up to a light and you see a little bit of smoke coming out from under the car. A properly set up system to direct it back to the intake like what NCHornet sells is still the best way to go

i vent to atmostphere and have to seen anyproblems from it yet plus it oils my frame so it doesn't rust out lol
