Ace, You might consider listening around the clutch throw out bearing or the AC idler pulley's bearing.

Since the weather got cold in AZ, I've got a loud grinding noise coming from the engine bay after starting up the engine for about 7 or 8 minutes afterwards. I can't see anything visible rubbing, but it sounds like metal-on-metal. It happens with or without the car moving, and RPM changes seem to affect it randomly. Any ideas on what to check? -Ace To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnews Yahoo!
