catch can?
A catch can is a metal can that installs after the PCV Valve and catches the oil vapors/oil that would normally be sucked into your engine to be burnt off.
I reccommend an AMW catch can. I installed one on my car and it is a wonderful piece of equipment. Installation is easy as well Plus they're a sponsor here.
