Hi everyone,
Thought I should tell you about a little problem I'm working through.
I did an oil change on the weekend, and found the following in the oil:

Doesn't look like bearing material though.
Fortunately we have a Niton Xray Fluorescence PMI gun at work that can do a chemical analysis on particles of this size:
