It amazes me the number of anti-catch can folks.
Some just don't understand the physics and think their daddy's Oldsmobile didn't need one, so by damn they don't.
What they don't realize is the Hemi has relatively higher compression and when combined with modern pistons that have shorter skirts and fewer rings, you get a bit more carbon and unburned fuel as blow-by entering crankcase. It volatizes (turns to a mist with entrained water and oil) and the PCV sucks it out. But who needs the knock, or pulled timing, and associated varnishing up all over the intake system.
They can save their pennies if they choose, but its stupid to bash a good product doing what it should. IMHO
