1. It is a means to reduce the amount of oil being pushed out of the engine from the pcv back into the intake/turbo.
2. Yes and no. If it's filling up, you have issues. You should only have to occaisionally wipe it out.
3. Yes
4. It can be placed whereever you desire so long as you have the ability to mount it.

 

I think he pretty much summed it up for you.
