Lots of time its only plating from chains etc! In such small quantities as in this example its not an issue.

Just emailed Cantrell Motorsports about this with pics, and they assured me that it is completely normal and nothing to worry about.

I think you need to worry when it looks like this.

Looks like an IMS bearing in an NA car ready to go!

metal does not belong in your oil filter. say what you will about worry ( don't worry ).

Well, actually, that engine was already gone at that point. By the time an IMS bearing gets to that point in an M96, just swapping out the bearing ain't going to fix it. It needs a complete tear down to clean up the debris.

Thankfully not a problem we have to deal with in the 996tt!
