Hi. I just had a friend over, and she said her 2007 Mini is making a clicking sound. She popped the hood and started it. I grabbed a mechanic stethoscope and started probing. When I touched it to this, it darn near blew my eardrums lol:


What is that? I'm no mechanic, but judging from the sound level I assume that is what is clicking. I had no idea what it was though so didn't know what to Google to see what trying to fix/replace it entails.
