Oil catch can

Hiya

I was reading a thread ages ago with lots of pics and info of OCCs but can't seem to find it now.

Basically looking for some examples, what's the best method

I.e. venting back into intake after filtration

or vent to atmosphere

or have vent to atmosphere AND pipe back into inlet.

I've got the elephant hose mod atm but would like to be a little more ecofriendly.

Any links or advice would be great, thanks!
