Without going into too much detail (the white paper does more of that), Here're a couple of tips:
1. Keep the catch can away from heat. The hotter the blowby gasses and entrained oil droplets, as well as the surfaces they contact, the more likely they are to squirm past the filter media. Synthetic oil is especially tough to trap.
2. Make sure the routing of blowby gasses is such that the last thing the air "sees" is the filter media. Many catch cans route the air through the media first, and then expose it to sloshing oil before sending it on to the intake manifold - not good!

Good to see you installed it properly and used the OEM PCV connection!!
I see so many people do it wrong by replacing all the of the PCV hose with the new hose that comes with the can. Then they are amazed at how much oil is in their can.

No joke! That's quite a write-up! Very interesting.
You've gotta admit though, that the massive catch cans look like they can do much more than that tiny little glass filter. After all, it's always said that Americans like big things!
Thanks for the education.

You're welcome. Designing an oil trap does go way beyond stuffing some media in a tube. The velocity of gasses passing through the filter is somewhat critical - too large the filter area = lower velocity of the blowby gasses. At some velocity, the oil droplets easily work their way around the media. So, for catch can filters, size matters and bigger is not necessarily better. Too high of a velocity will encourage droplets to be "retrained" into the airstream - not good, either.
As far as the can size goes: Having a large can for the sole reason of not having to empty the oil can be self-defeating in that blowby gasses that have to pass by a large volume of sloshing oil are bound to pick up some of that oil. This is especially true of large diameter catch cans.
