I am thinking of doing the CCV mod, but the idea of just venting the oil vapors onto the back of my truck frame or elsewhere doesn't sound like all that great of an idea. BUT but one of the car mags did an awesome crank vent mod using a breather canister for a dry sump system at bout 55$ JAZ 1-Quart Breather Tanks - JEGS it could be remote mounted on the core support, or I saw this item, JEGS Air Oil Separator - JEGS it could be plumbed in between the CCV and the intake inlet? and then bolted right onto the bracket that supports the crank breather tube that is stock on the truck. I like this as it would make everything very clean and easy! both of these are from Jegs.
id have tio agree with you on the dumping it somewhere thing... not that its going to hurt anything but people have reported an awful smell... good idea
as our trucks sit right now without the mod... its venting all that wonderful stuff into the air intake tube... Oh and glad to see a fellow northern cali chap. member over here
so what are the advantages of of the ccv mod? i'm trying to figure all of this stuff out... Sorry to jack the thread....
CCV dumps oil into the intake tract on the 7.3. This induces oil in the intercooler system which causes oily/dirty intercooler boots.
The second advantage here is where the CCV enters in the air intake blocks some of the available space, causeing the intake to be less efficent.
To add to kawajockie's comments, which are correct, the vapors ingested back into the engine also displace the equivalent volume of fresh air, which results in a slight reduction in excess oxygen.
As for the vapors, if the hose is extended to the rear of the truck near the spare tire or fuel tank, the odors are generally not an issue, but you still get varying degrees of smoke from the re-routed tube depending on how much blow-by you have and which oil you use.
As for a trap, I have a picture of my own home-made trap in my gallery. PVC parts from Home Depot. many others have done the same thing with varying shapes and configurations. Guzzle has a good right-up on the same issue. Additionally, a few guys have taken the vapors from the trap arrangement and simply run them back into the intake in order to get rid of both the vapors and the smoke while simultaneously eliminating a majority of the oily stuff that makes the intake and boots so nasty.

The first one would probably work Ok, at the end of the hose, to eliminate the drips from the CCV hose and some of the smell. The second looks like the port sizes would be too small to put inline with the 3/4" hose required for the CCV. The second would be similar to the homemade I already have. It returns back to the air intake and acts as a separator.
So here,s another question, the black hose that goes from the doghouse to the underside of the intake tube, plug this because you wont need that hole no more?

If you just plug it, you run the risk of pressurizing the crankcase- not a good idea.
EDIT- were you talking about plugging the hole in the intake coupler? Go buy a 3" PVC or ABS (PVC is white, ABS is black) pipe coupler, or use some 4" exhaust tubing to fill the gap and get rid of the CCV intake coupler.
I need to figure the right route for me, I think I'm going to go with the catch can way. I had the intake tube off just last week and all the bottom side of the entire intake was coated with oil. Luckily I had a solvent tank near by and just let it sit for a few minutes. I need to do something, no sense in cleaning it up if I'm going to have to do it again.

Yes you must plug the hole on the intake tube, or remove the bracket where the hole is and replace it with a small piece of 4" straight pipe. You'll attach your 3/4" hose to the dog house to run the CCV vapors toward the back of the truck. Make sure the hose has a down hill angle to it so it doesn't freeze up in the winter.
This is my next mod for the fall season after my son's football season is over. Have most of the Home Depot parts and I'm planning on the trap and routing back into the intake.
I did this, turned the dog box around, used the rubber 90 from the stock d-box and join the heater hose and loop it over the brake master cylinderto keep the oil blowbye in the tube to return to the dogbox and routed straight down next to the axle, no oil drips yet. Up in the middle of the pic going to the master cylinder on a incline..
