PCV jar not working as expected

[Flatland2D]

I made a PCV jar out of some PVC using silica and some BB's as the catalyst. The problem is the hose going from the jar to the PCV valve is collasped under vacuum. Shouldn't this line be under positive pressure? Also, air is coming out of the hose from the manifold to the jar. Essentially it's flowing backwards. Do I have the concept wrong? Shouldn't air be flowing from the PCV valve to the intake manifold? After a bit of driving the inside of the canister was pretty much spotless with no oily residue that it should be collecting. It smelled like exhaust but that was it. What's wrong with my setup?
