CCV Mod Questions

[my19997.3]

Have a question about the mod. I have been reading as much as I can find, but no one can answer the question in any of their write-ups. I've seen where some take the hose from the CCV to the rear bumper (22 ft of hose) and others take it to anywhere between the middle of the cab to the middle of the bed.

1) Should the hose be long or short? Advantages/Disadvantages?
2) Can dirt/debris/dust/etc get into the end of the hose and work it's way back to the motor?
3) Should a small filter or even a piece of pantyhose be placed over the end of the hose (exit side) to prevent anything from getting in?

I did the CCV mod on my truck and i put a pice of hose about 3' long on it and ran it down beside the motor to behind the Drivers side front tire, but that puts off alot of stink. So I moved it to where its blowing under the cab and i dont smell it as much. I would like to run it into somthing to keep it clean, the panty hose idea seems like a good idea. I saw where one guy ran his into a can with some scotch brite in it to absorbe the smell. Thats why folks run theirs to near the bed. Iv also thought about intalling one of thoes old style chrome breather caps that used to be in the old chevys and fords to vent out the engine.

I was thinking either the pantyhose or a small breather filter like I used on my old beater truck ('78 F-150) in place of the PCV. I can get one of these at Autozone for like $12 but wasn't sure if it would do anything. I figured I would just use a hose clamp to hold it in place and tuck it againest the frame with a zip-tie.

save yourself some time and hassle and just send NChornet a pm and buy one of his ccv mod kits for cheep. I just got done doing just that. He put a ton of research into his kit and everone that has it has said that it works fine. I recall many post of DIY ccv mods gone wrong. Just my .02

Thats the same thing i was thnking about doing. That would keep the smell down and keep it clean.

I wonder what size the hole in the valve cover is? If you could put a rubber grommet in there and just put the breather right in the valve cover just like the old trucks.

You might get the smell back to the cab much like you do with the dump to the fender.... not sure though

That would make on heck of an oily, smelly mess! The whole idea of the CCV is to keep all the nasty oil laden vapors out of the intake and intercooler. With just that vent you would be blowing that crap all over your engine compartment.

I have done a few on 7.3s by just simply dumping a short hose down along the frame but it smells and on older units will smoke from under the cab. Ours are just work trucks so I didn't take the time to do it right, but I will do my 6.0 up right if I ever get around to it.

Buy the long hose and route it to the rear. No smell and it surely won't get anything back in it to the motor.
