Which check valve do you recommend using? And where should I fit them if using the AVO breather?

By the way I'm confused about how to hook up the 3 ports on the breather tank. I can see from pictures that 2 of the ports will be used to connect to the breather. But what about the rear PCV to intake manifold? I'm assuming something needs to be blocked off then?
