CCV Mod - atmosphere venting

[neil]

I was toying around the the idea of doing the CCV mod on my 2005 F250...and now I sort of must do it.

On the short intake tube that connects to the turbo...I, through years of experience, thought the rubber grommet that the angle cut vent pipe pushes up through was actually a grommet. But its molded into the tube itself through some process.

I was trying to remove it and instead it tore off. I was using alot of force. So now I've got a tube that can't accept the vent pipe any longer. Suppose a trip to the Ford parts man could cure it well enough.

Anyhow...my idea was to vent to atmosphere nonetheless. I've owned 2 Cummins Dodges and a Duramax...and all were atmosphere vented from the factory. I usually extended them a little to get it away from the fan/radiator but the "smell" or oil dripping was never really a problem. Perhaps once in a great while I'd see a drip or two on the garage floor. Not often.

Are atmosphere vents for the 6.0L any kind of problem at all? I was going to use black silicon heater hose in the 1" ID size. Its oil resistant, bends easily...yet is a little costly but worth it. At that size...it should vent well. I was going to run it down to the bell housing area under the truck.

In my experience on pickups and big trucks...no real quantity of oil comes out of them which would make a huge mess or coat the bottom of the truck. If it were this way...we'd be losing oil on the dipstick and have to add. Thats never been the case for me.

I had a lot of oil smell in the cab until I extended my CCV hose about 6 ft down under the cab. I used clear vinyl hose. I know there is a vapor coming out of the hose , however I have yet to see a drop come out of it.

Mine vents to the atmosphere via a 3/4" hose that is solvent stable and extends to about 2 ft past my HFCM (fuel pump) on the driver's side frame rail. I added an old school breather to the end of it just to prevent anything from getting in there or spewing oil everywhere. It seems to work fine with hardly any smell.

Thats what I did, I bought a 16' hose, ran it to the rear axle and dumped it. It has a short pipe/bushing inside and a metal screen on the outside held on by a hose clamp. (To keep bugs out.) Gets a little smokey if you run it inside.... but hey, so does your exhaust.

I plan on doing something similar but I live where the winters are cold and I worry about the vent piping frosting closed causing seals to blow. Once I have an all weather CCV system built I'll post some pics. At present it is on the bottom of my to-do list.

I crack my ccv canister every other month or so and it will drip out i'd guess anywhere from an 1oz-2oz of oil. I have it coming out of the cc and down under drivers side framerail into a collection canister, and then routed back up into the intake. I'm always suprised at how much will drip out.....

[ToMang07]

Mine must all come out when I'm driving.. I never have any drips on the ground...from the CCV.

Just out of curiousity FourFun.....why'd you run it back up to the intake?

[FourFun]

It was a kit i bought. I wasn't sure how much oil would come through and i wasn't crazy about the idea of oil dripping on the driveway. I wanted no chance of it, that way if the truck starts leaking oil i know for a fact it won't have anything to do with the ccv leaking/dripping. I guess its ocd

[sinner6.0L]

it's also a good idea. ported vacuum from the intake bellows will scavenge crankcase gases out of the engine

that's the way i would run it. just route in a catch can to keep the cac tubes clean

I drain at least a cup of oil every oil change from my ccv filter. Glad I have it. I have 1" hose from the vent to the intake tube w/ a Racor filter at the drivers side frame rail.
