Yesterday while performing my oil change I noticed something in the bottom of my oil tank tiny black fragments the size of a lead pencil non metallic along with a few larger pieces that had a concave shape on one side I questioned a few techs and the told me it was probably the cage on the main prop shaft bearing so I took the gear box out and the bearing is not damaged . I've been looking at parts book and I'm starting to think it might be a valve seal has anyone out there ever encountered one of them breaking . I will remove valve covers today hoping to find were this is coming from Thanks for any response you might have for me.Picture of fragments below
