What is this little thing a guy found inside his 2.8?

Okay, so a guy on the norwegian Audi forum was doing some routine maintenance on his A6 2.8 V6.

He found this:


And then this:



The part in the last picture did not fit where he was missing something.
The part number on it comes up as a FAG BMW E34 rear axle wheel bearing..
It sort of looks like the inner circle on a wheel bearing aswell.

Well that's pretty nuts, all that material chipped off and then a foreign object inside..... Bulletdodger!

And no damage to main components?

Well I've found some odd things in sumps (normally small sockets etc) but one really has to use some imagination to work how a lump of wheel baring got in there, I agree that's what it looks like.

Being cynical I am guessing somebody deliberately dropped that piece in his engine to screw it up, it certainly didn't get in there by accident.

One theory is that, as the 2.8's are prone to cam chain tensioner-failure, somebody has wedged this under the cam chain

Probably a BMW owner (insert tosspot smilie)
