First off, thanks for the replies.
The 'strange' noise is OVER and ABOVE the normal "dieseling sounds" the LWFW makes at idle. I first noticed it between shifts, then I tried coasting without being in gear, and now I have more evidence.
I was hoping for a rock but I started the car yesterday and heard the noise at idle. I would record it but the noise is un-nerving!
Looks like I'm going in.
Prepare the patient for surgery!
