I bought a spare Alren Ness backplate and modified it to reroute crank pressure gases away from the intake. It has two barb fittings so you can run tubes to a catch can or to the ground. I ran mine down with the fuel tank vent. I went with an entirely different intake and already sold the rest of the kit.

I'd like $30 shipped for it.

Here it is on the Arlen Ness site:

Total: $74.09
