PCV system

how do you know if the PCV is broken?

whitezombie, on jegs.com it says the black wrinkle finish is for 383/440 only, and the chrome ones are for the 318/etc, do they fit well? i was going to get the mopar performance breather kit (only in black 'wrinkle' finish) and the valve covers to match it (once i get to the engine work.)
