Do yourself a favor and don't run a catch can. Easy way to cause to much crank case pressure and leak oil out of all your seals.

Very easy to do- just turn the CCV dog house around, use new orings when reintalling or it will leak. Twist the 90 degree fitting upwards to about a 45 degree angle, insert a heater hose coupler, connect either 3/4" heater hose or fuel line and extend it either straight down,
or run it out towards the back of the truck. Be careful to avoid any low spots
that can collect fluid and restrict the air flow. This can cause excessive in the
engine. Plug the hose connection on the intake tube. Clay has some very good instructions for his CCV kit that can be adjusted for the OBS trucks.

Just to add another idea.
I have mine vented right next to my 6637 filter. I used 3/4 heater hose and ran it to the filter where I tied it to the filter mesh. I attached a cheap Mr. Gasket valve cover breather to the end at the 6637. The intake still sucks the fumes right through the filter so no fume smell in the cab and I don't have any oil messes.
Been running it for about 1500 miles now with no problems. I can get pictures if anyone wants, its not the prettiest but that wasn't what I was going for.

I understand why everyone says "turn the dog house around" on the valve cover.
I tried this and the 90* fitting would hit the fire wall. Not sure if my truck is different, but there was no way it would fit.
So I left it in the stock position, facing forward, and put the 90* fitting on and ran the hose down under the brake lines and junk. You can't see it because the intake pipe is above it.
Also, with this "vent to atmosphere" concept.... it freakin smells. And every once in a while I will be standing next to the truck and there is a fog coming out the hose. But only once in a while.
But the smell.... gross.

Has your truck ever been wrecked King? The CCV housing shouldn't touch the firewall. The smell is the reason a lot of guys run the hose as far back as possible. Your oil brand can change the smell too. When I ran Motorcraft oil in my SD it stunk to high heaven, switched to Rotella and the smell all but went away.
Catch cans, when done right, can work, but they MUST be vented back to atmosphere and then you have to worry about draining them all the time. Since I'm not intercooled I haven't messed with the CCV mod on this truck, not sure which approach I want to take.
FWIW, the IH trucks that had the 7.3's were vented to atmosphere.
