yeah, I agree with most of what you're saying ...
the proof may lie in the PCV SCFM rating ...
I would disagree on the point that the filter is being used for a purpose that it was not designed for ...
the manufacturer's description says that it is "... a general purpose filter [that] is designed to remove most liquid and solid particles from the air supply."
it seems to be doing that satisfactorily ...
at the risk of sounding too "unscientific" ... do not all filters clog or otherwise lose their effeciency? of course they do. Is an engine DESIGNED to run on a perfectly clean, brand-new air filter? what if that air-filter is slowly clogging? after 50 miles? after 100 miles?
what about oil? is a system DESIGNED to run on a brand-new filter? should we be sceptical of that system after 50 miles? after 100 miles?
hmmm ... our air intakes were not DESIGNED with a CAI, "cone-type", 360 degree filter in mind ...
more ideas!! keep 'em coming!!
anyone on SCFM ???????????????????????
would the SCFM of (a particular make/year) a PCV system be the "proof" ???

I wish I had one in my hands - However, all I know is that filters clog. It is only a matter of how fast. This is a filter that is being used for a purpose that it was not designed for in a system that was not designed for a filter - Also the system that if flow is restricted, crankcase (oil) contamination increases.
I am much too cautious to do this type of mod without having some way to test if the filter is clogging. Maybe replacing the entire unit (if that's what it takes) every 10k or so for peace of mind. Maybe back-flushing the filter with solvent periodically would be enough. I know that the old gasoline filters I mentioned above could not be cleaned by back-flushing. You had to throw them out once you got fuel starvation.
Maybe nothing is ever needed to keep it free-flowing. You guys will find out.
