Oil Catch Can Discussion

Hey guys, I know this topic has probably been beaten to death, but the more I look into a catch can the more confusing it gets. It seems like most people are afraid to vent the catch can to the atmosphere. Is it because people don't want to get into trouble for the environmental aspects, or are they afraid that the crank case won't be able to vent adequately without vacuum being pulled on the system? I found a picture from speed hunters of a car that seems to be venting out of a oil separator to the atmosphere with no catch can at all. Has anyone ever seen this done, or have any opinions on the viability of this set up. I am currently trying to come up with a catch can solution, and as I am sure you all know space is a premium under the hood of a gtr without having to relocate the battery etc. Any opinions on this set up, or a good mounting location for a catch can? Thanks.

There's some recent catch can conversation here: https://www.sau.com.au/forums/topic/193576-do-i-need-a-catch-can/?page=2

Re atmo venting, it's not legal, hence the avoidance. From memory, I also read somewhere that it can cause oil residue in the engine bay.

1. Its illegal

2. You can get unwanted smalls in the cabin

3. If you don't monitor it you may be dropping oil on the track which will make you very unpopular.
