There has been threads on this discusion and from what I read, it isn't a good idea, a bump for more solid answers.

I believe it creates too much backpressure.

And you'd probably want to not use the bung on your downpipe for your pyro. That's post-turbo and typically it would be mounted pre-turbo.

Shouldn't be an issue as long as its toward the end of your exhaust (after muffler)..

I have mine plumbed into the fresh air vent that goes into the cab.

Otto -- that has been tested with pressure/vacuum gauges on the engine, and the pressure goes *UP* in the engine when the CCV is plumbed into the exhaust, no matter how or where it was done (yes, even at the end of the tail pipe).

I would strongly suggest you avoid doing it. Mine is run all the way out by the tail pipe through a hose, and so far, no issues. It was the first mod I ever did back in Feb/March of '07 -- shortly before I met you down in PC. It's still there and still working...

For a little more work and a few bucks more you could have a closed system that does not stink when you are sitting at a light.

For example (photo):

You could vent it through the exhaust as long as it was introduced via a venturi. Very simple, just some mild metal work for the exhaust pipe. Then the flow of exhaust, through the venturi (pressure gradient), would create a vacuum for the CCV.

I think you may have a problem at idle or low speed, not enough exhaust flow to creatate the pressure gradient needed to make the needed vacuum. just my .02 cents

Thanks bfife. The collection unit can be ordered from McMaster-Carr online. Here is a link to it:
McMaster-Carr

It is the Nylon T-strainer with clear bowl. I use the 1.5 inch opening port unit. I ordered it with the 40x20 mesh screen which is a larger opening mesh screen. I believe the percentage of open area is between 40 and 50%. The screen is just a clinging surface for oil in the vapor stream. The lower the number screen selection, the larger the mesh opening. A couple other forum members wanted me to do a complete parts list with fittings, reducer connections and barbs. The entire set up. I said I will get that done. I will be doing that some time in the next week.
