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.

Yes, mine is a 2.7 x5 chain 2000 car. Apparently the variocam actuator has these green seals hidden inside the body of it (so visually telling if one was as bad could be hard).
The weird thing is, before the oil change (and some of this was found in the filter) the car ran good and it starts and is not erratic and I dare say it will still run. From what I have read the variocam is operated by an electrical solenoid triggered by the DME or ECU and therefor will still cut in even though the seals are worn away and I am hopeful the particles have been collected (partly) in the filter? There are no warning lights and I wonder if it is OK to run the engine and see? I have been advise to flush the engine, check filter and if particles still there to have it taken out + opened up...My opinion is the bits are rubber, soft, pliable and won't damage much as they are tiny too (although I was told the intake screen of oil pump could get blocked?).
