I think you are talking about the CDR valve (Crankcase Depression Valve) There is a diaphram that lets the gas/air thru and when pressure is built, it stops oil from entering the intake.

But others who actually know how it works wil chime in soon.

if there's something rattling inside, sounds like the diaphragm is busted and letting that piece move around. just a thought.
