Everytime I change my oil I see little bits of brown plastic in the filter element. This looks like Vario cam tensioner pad material. Does track driving cause more aggressive wear of this material/component? How long do I have before I loose proper actuation and phasing of the cam shafts? What will the tell tail signs.....perhaps minimal power change through 4000 rpm?

Has anyone had to replace these things?
