The problem with these trucks is that they use a system that routes pressure, gases, and incidentally oil "mist" from the crank case back into the intake to be burned off. That's what a PCV valve is for...to release the pressure and subsequently the gases and oil. A catch can goes in-line from the PCV valve and intake and is designed to catch the oil. The BT can is dual chambered and has a filter element inside which causes the mist and gases to condense. When it does, the oil droplets drop down into the bottom chamber, which is what you unscrew to dump the oil. Basically this keeps oil from the crank case from going into your intake and ultimately into your engine.
