Hey guys, I noticed a rattling noise coming from around the alternator about a week ago. I had just turned the car on to move into the garage and the noise started right away and got a little louder as it idled. Once I moved it into the garage it had stopped. That was really the only time i heard it while at idle. Now I only hear it when I start moving from a stop. It kind of seems like you can only hear it when that initial load to start moving is placed on the engine. If I ride the clutch a little longer, you won't hear the noise. If I try to take off hard, you'll hear it. Anyone have any ideas? Thanks in advance for the help.

Clutch, pressure plate, throw out bearing.. etc. My guess is if you have a oem sprung clutch one of the springs has come loose...

Time to drop the tranny...

I really hope it's not the clutch but i'll keep it in mind. I do have an update though. I made it most of the way home from work yesterday without hearing the rattling. Then I turned on the AC, and I started hearing it when I would get going from a stop. If it was the AC compressor pulley or the compressor itself, would my AC still be working? It seemed to be running the same as before the noise.

Check the lower alternator bolt, if that's good check the bolts for its bracket.

I didn't notice anything major. I checked out the belt tensioner and saw a small bump in it's movement with the AC off. When I turned the AC on there was a slightly bigger bump in the tensioner and the belt started to flutter going from the alternator pulley to the AC compressor pulley. This was all at idle and there wasn't any noise. I'm going to start by replacing the tensioner and belt and go from there. At 125k miles these parts have never been changed so it's overdue anyways.

Update: I replaced the tensioner and belt yesterday and so far that seems to have fixed the problem. The new tensioner was definitely harder to move than the old one, and the belt had cracks over the entire length so both were really in need of being replaced. Hope this helps anyone who has the same symptoms.
