Build A Catch Can - Step By Step

With a little ingenuity and the right tools, you can make just about anything you need. This month we burned up some aluminum in an effort to make a homemade catch can. More specifically, we will use this as an air/oil separator for one of our cars' PCV systems, and we did it with scrap aluminum from our local metal-supply warehouse.
