if you are indeed talking about pvc libe that usually goes from the rocker cover to the inlet mani you should use a catch can.
the idea of it is to vent positive crank case preasure.

a catch can will catch catch oil that usually would have got back into your inlet mani and hence into your engine, lowering your octane rating of the fuel and taking away hp, and making your plenum all dirty and **** on the inside.

You can either vent the catch can to atmosphere (via the filter you speak of) or run it plump back into the inlet mani.

ok so the arrows are pointing to the catch can (that one i made but you can buy them easily enough) the larger hose comes off the rocker cover, the smaller one is a direct crankcase venting line, and as you can see i have the filter on top so it vents to atmo. Inside there is baffles so the oily air simply cant go straight out the vent is has to negotiate its way past plates and so on, this causes the oil to catch in the bottom, and not go out the filter.
