Hey Merrill on those catch cans your selling with the material inside, what is the material (filtering product) that is contained in the canister?
Also I would imagine that the material is replaceable so when it gets clogged with collection of the crank case stuff. (if I'm correct)


I think some also use the catch can to catch the heavy materials that fall in from the case and though having baffles is a great idea to stop the direct return flight into the motor, most the heavy material will drop to the bottom of even an empty canister and not be sucked back. I agree on the restriction, if your restricting the line flow through a fitting or hose, this is not a good idea.
I use one on a car I have and it seems to work very well being empty. I'm not sure if it is fluke thing, but it's doing the job.
I also am exempt from any smog requirements due to vehicle year fall off.
