Is this the first time you've inspected the medium? Have you ever pulled the sump cover to see the level of debris in the sump? Are you due for a clutch change or other engine-dropping, tranny-dropping work (just replace the bearing at the same time)?
For the two years I've owned my 997.1 C2S, I've opened the filter and saw a range of quantities of metallic specs - almost always non-magnetic (but not always):
-peak - about 6 specs per square inch
-avg - <= 1 spec per square inch
I've put 15k+ since buying it. I use DT40 with a splash of DT50 in the summer. No unusual noises or other symptoms indicating IMS trouble.
When my clutch goes, I'll put in the IMS solution if I have a replaceable bearing (not likely with my serial number) or I'll remove the seal on the non-replaceable bearing.
