How does a oil catch can work?
 

I searched but it only tells me what it does and not how it actually works. And also what happens to the oil when its stored in the can? Thanks.

Anyone know?

At least tell what happens to oil when it stores in the catch can. Does it have to be cleaned out or something??

here you go, lazy.

Oil Catch Can

......you can even copy and paste them in.

Thanks, but i already knew that info from the link. That still dosent answer my question, what happens to the oil that gets stored in the tank.

Never mind, found an answer to my question, yes the catch needs to have the oil emptied out. Thnks.
