The proper method is to dump the oil back to the sump or collect it in your used oil containers for proper disposal. Imagine if all vehicles would do the same dumping in the road, well end up with oiley pavement just like in the early40s where its not illegal yet to vent those unburnt gasses. BTW those provent have a bung designed to route bak the oil to the sump.

I fully agree with this.

Oil mist is somewhere in 0.3micron, unburnt gasses is on molecular abt 1x10-3 micron, while the regular motor fuel cock filter is nowhere 25microns. So no, the gasses and oil would just pass that tiny filter. You need something finer with coalescing element and insert back the gas to intake manifold for further burning.

+1... You'll need something like an activated carbon filter to catch those tiny hydrocarbon particles.
