NA Crank Case Ventilation Question

Ok, so with all of the rat's nest gone I was left with some oil misting on my engine. El Nene had me pick up a breather for it and I rigged up a little contraption however, it's a wee bit ghetto for my liking. So I would like to see some setups from you guys who are running NA's with no emissions. And not venting it back in to the motor via the intake vaccum nipples.

What I am looking for is something that allows the oil to go back in to the "crank case" directly but still allows ventilation so I am not having an issue of excessive oil pressure. Is there a breather that allows the pressure relief but won't allow oil out? Am I looking at running a catch can much like you would on a Turbo motor? Give me some insight, some ideas.

Oh by the way, I rigged it not El Nene!! Everything he did on the car was very clean and professional.

Just run it to the dynamic chamber. The engine just ingests it. If not just get a long vacuum line and run it into an oil catch tank. Maybe hook the cold start assist tank back up and run a long vacuum line into it?
