Is this actually a valve (since yours is broken into pieces) or is it just a metered orifice? I know a lot of engines don't have a valve anymore and just have a metered orifice. As long as quality fuel and oils were used without excessive change intervals there should be minimal opportunity for buildup to clog the holes.

Nothing to tell, you guys have proven it is an actual valve still. Some manufacturers (like on my Traverse, for instance) have moved to a "metered orifice", AKA something that looks like a PCV valve but is completely empty inside. The size of the holes on either end speed up or slow down the vapors. A common mod on the early LLT V6 Traverse is to drill out those holes to slow the vapor down, thus letting the oil settle out rather than getting sucked into the intake. On a direct injection engine, little mods like that can make a big difference in intake valve buildup.
