Same here, but about 15' of 1" hose got to just behind the cab. I never smell it, but I can see it puffing if the light is right.

It is probably not a big deal if it is anything from 90 degrees to being angled.
The worry I have is this --- do you really want to do that?
Exhaust pressure is, IMHO, higher than CCV pressure --- are you liable to have the gases blow from exhaust back into the engine?
Even with a one way check valve --- you may have an overpressure problem.

The theory is that at most flow rates, the exhaust will create a vacuum on the CCV line if the bung is welded in at the right angle. Remember Mr. Bernoulli? 
That way you have your single-point exhaust solution that the EPA wants, and keep your intake tract clean, like everyone ELSE wants.
(on edit: CCV gasses have an odor? Who knew???

I am not so sure the theory works so well.
You got exhaust back pressure from the muffler and the cat, unless you plum it in the very back.
Furthermore, EPA wants the dirty gases from the crankcase treated -- not just dumped out the tail pipe.

Again, if I remember correctly, the issue wasn't getting CCV flow; it was finding a welder who could do the job correctly, and the proper location in the exhaust pipe.

Ahhhhh, here's the thread:
https://www.ford-trucks.com/forums/7...light=bung+ccv
The thread originator backed out of the weld attempt. But the theory does appear to be sound.
The parts listed from Moroso (via Jegs) and the accompanying install instructions show how. 45 degree angle. The instructions show a pic with a V-8 gasoline engine, running a tube from each valve cover down to the accompanying header collector.
I'm inferring here from the pics that any application that requires NO leaking (drag and/or circle track, in this case) can easily use this to keep the drips off the ground. Note that these are also both applications where open pipe is used (i.e. no muffler).
I wonder if the breather caps supplied in the kits would perform sufficient coalescing to eliminate the drips, even if one did not weld into the exhaust?

I would just go to a Marine dealer and find a Parker-Hannifin part to fit.
They have a full line of CCV filters.

Big Buck$ there, on a part that COULD get axed by the inspection *****....
For me in this case, it's either factory part, or vent to air... the hassles/costs of doing it any other way are counterproductive in my book... $400-$500 (est) for the P-H part, and trying to figure out where to mount it...
