For a catch can to collect metal through something like this, it would have to be pulling copious amounts of it from the valve cover area. Most of your PCV locations are above baffled areas of the valve covers. The oil that's being sucked up is what's available in splash, or a vapor that's condensing.

I agree... I'm on the C6 Z06 boards and it's quite common. Like Brent said, most think it's coming from the "brillo pad" type filtering media in the can or the machining process.
