What exactly does it do, I think i remember it does something like recirculating the unburned gas mixture back into the combustion chamber iirc?

Also, is there any kind of maintenence on that, ie: ne thing you need to keep cleaning internally or such, not getting one, just curious.

It recirculates or just catches oil depending on how you set it up. Powerful turbo engines when at full throttle get blowby and oil comes out of the valve cover. Normal cars have it recirculated into the intake which sucks. This lowers the octane of your gas and can create potential problems especially on a powerful turbo engine at full throttle. The same could be said for NA engines but not to the same extent. Basically, it just makes sure you're not getting oil and oil vapor in your intake air.
