CCV mod Questions
I am sure you guys are getting sick of the same old questions but I am new to the PSD's and I don't wanna screw anything up. I got my 6637 filter and I am hoping to get in in this weekend, but I want to do the ccv mod at the same time and I want to make sure I am going to do it right. Do you just route a hose from the valve cover to somewhere towards the rear of the truck and plug off the intake end? I have read all of the posts on this topic and this is what I have gathered, but again I want to make sure I am doing things right. Thanks guys

Do not plug off the intake end, remove the black plastic piece in the intake tube that the ccv originally plugged into. replace this piece with a 3-5 inch piece of 4" exhaust pipe. Make sure you clamp the intake tube ends down good. run a piece of 3/4 heater hose over the rear of the master cylinder and route it to the middle or rear of the frame of the truck. Now you can go as far as to turn the CCV doghouse around on the V.C. or you can leave it with the outlet facing forward. Its up to you.

Here are a few pics of how I did mine. You can see the short piece of exhaust tubing that replaced the black plastic CCV return in the intake tubing. You can also see the doghouse on the valve cover, and the hose coming off of it. I oringally had it routed to the rear of the truck by the bumper, but now it just runs to right below the driver's door.

I read Guzzle's How to on this subject it is really good. But it doesn't really explain in too much detail what the advantages of this mod are.
Also to do this mod on the wifes 7.3L EX I would assume it would be a no brainer that you would have to run the hose all the way to the back. Are there any disadvantages to doing the mod this way??
Thanks,
JB

The advantage is that you keep the oily gasses out of your turbo, intake, and I/C. When the intake boots get oily, they can pop off easily when under heavy boost (even stock levels). As far as running all the way to the rear, that's your call. I've heard that moisture can get in the longer runs and freeze in very cold climates, so keep that in mind. The benefit to going to the rear is that the stinky fumes are away from your windows. Mine is run up over the brake booster then down to the passenger-side tie-wrapped to the rear axle by the exhaust. The goal is low back pressure, so you don't want any restrictions on that hose...

That explains it! I recently had to replace the injector wiring harness and in doing so I noticed ALOT of black looking build-up in the intake housing. The edge of the fins on the turbo are also damaged/bent slightly. Think I'll do the mod today!

Thanks for the info. I'll look into buying the wheel! I currently have 107k miles on my 2000 Excursion two wheel drive. Would it be more economic to buy a new turbo? I'm not sure what the life span is on these things...
