I have a 5 chain-engine, with a different cam-actuating system. On that one, a simple thing you can test is the coil for continuity with an Ohm-meter. I`m just rebuilding the heads and got a used actuator from eBay, so you may find a good one there too. I don`t know about the 2.7 actuator, but the 2.5 has no such part that could produce the debris you found in the filter, at least not in such amount. It`s hard to tell though based on the picture. Maybe once you remove the faulty unit from your car and inspect it, you`ll be able to tell what to look for on a used one before you buy it.
