I run webers on my B20 (now out to 2.5litres) on my 144 rally car.I run a hose from each of the rocker cover and the breather into a y piece and then on to a catch an mounted where ever you can. In my case, it's next to the radiator. Local race rules means it has to be 3 litres because the engine is over 2 litres. A challenge to fit something so big in the engine bay.
We've done several long distance rallies without any problems. It's certainly not legal from a vapour control point of view.
