CCV question
The ccv on the 7.3 dumps right in to the air intake, which gets pulled though the motor and out. Could there be a reason that they dumped it into the air intake. I was thinking that it would lub the engine where oil can not get. I don't know if there is any real data to back this up but it was my thought that the Ford engineers just were not being lazy when they vented it that way.

7.3s in international trucks have the ccv already routed down the back of the block. Like David said treehuggers are the reason those fumes are sent into the air intake, to try to keep them from going into the atmosphere.

Looks like it gets into the atmosphere either way (burned or not).

All you need to do is flip the dog house (metal housing on the valve cover), go to the hardware store and buy a straight barb adapter (1/2" I think? take your dog house in with you to match it up), a long piece of rubber hose (auto parts store) and some hose clamps. Then you need either a piece of 4" exhaust tubing or a 3" ABS or PVC pipe coupler to replace the CCV housing in the intake, or rig up some way to plug the now open hole in the stock CCV housing.

It's actually 3/4". I did the same thing and worked great. I'll get some pics of mine tonight and post. The 4" filler piece in the intake I made so it bolted back up to where the stock piece did. Used 4" exhaust tubing that was 3" long. Welded a piece of flatbar to it for mounting. Masked off the ends where the rubber gets clamped to it and painted it black.
