I have mine vented to air behind the fuel tank. Works great!

CSIPSD,

Thanks for the input. I found a kit wtihout the accumulator for $80.

From your signature you have done a lot of mods to your rig. Were they for performance or fuel economy... Can you break down these mods and what they did for you?

You don't have to buy a kit. You just need about 5' of 3/4" heater hose, and something to plug the hose on the intake.

I just ran mine down behind the front wheel. I haven't noticed and performance or better mpg though. It does let your boots stay cleaner.

man I need to do this... likely will do it when I install the 6.0L IC

Where can you get an accumulator?

I think it might be best to keep the line short, and place an accumulator near the master brake cylinder.

If doing the mod is supposed to keep the intake tube clean, then why would I want to vent it near the truck (front tire wheel) and dirty the bottom of the truck? If the hose can fill up with junk, I don't want to run the risk of the hose plugging by running it to the rear.

I don't understand how the engine compartment gets dirty when hooked up to the intake. Doesn't the intake receive the CCV and recycle it? So how does it get all over the engine compartment?

If the hose gets plugged, seals leak. I'm not sure if the seals leaking are permanent damage, or if unplugging the hose would remedy the problem and no harm done?

More information is available at BD CCV Kit

Holy cow! Who is going to spend $335 for this kit?? It's a nice kit...but way too much money. I'd pay $50-60 for a kit like this. For anything more, I'll just run a hose to the back, or figure out some DIY. Maybe someone could come up with a part list for us DIY types.

BD makes some good products, but there is absolutely no reason to pay $335 for something that shouldn't cost anymore than $5. If you want to put an accumulator on to be more environmentally friendly, you can make one out of PVC for probably $25. Do a search over on PowerstrokeNation.com. There is plenty of information on there about how people have done the CCV mod. Personally, I just ran a 3/4" heater hose down by the back drivers side front leaf spring mount. The only time I can smell it is if I've been runnin it hard and have the windows down at a stop light or drive-thru. Otherwise I never smell it or have any oil drippin. Don't forget to plug the spot where it goes into the intake tube. I just bought an assortment of vacuum caps at Autozone and the biggest one fit perfectly.

i did it and recommend it. however, route the vent hose to the back of the truck or tap into the exhaust. if i dumps under the cab, it stinks up the cab at idle
