Who's running a catch can?

The factory setup is that, separately on each side of the engine, one hose flows outwards from the crankcase to a manifold vacuum inlet,

So these are the ones toward the front of the engine that connect to the two V shaped nipples on the front of the manifold. They flow OUT from the crankcase to the manifold?

and the the other hose flows inwards from filtered intake air into the crankcase. At least the vacuum-connected ones have PCV valves on them, I'm not sure whether the fresh-air-connected ones have a valve buried in there somewhere (or perhaps just some foam or something).

So these are the ones that connect from the intake tubing through a plastic baffle and then into the valve cover? Where/when is the air recirculated back to intake then?

So to run a dual-can setup, the normal way would be to splice one can into each of the vacuum<-crankcase lines.

So splice a can in between each of the red hoses pictured here:

I'm confused now
