Hey guys

I was hoping you'd be able to help me diagnose a strange sound coming from my car. I've done some work to isolate where its coming from. It happens in the following situations:

3100rpm only
Every gear
Off throttle only

About my car...

1997 hx 5 speed 212k miles
Good maintenance record and I have owned it for 8 years
Clutch has not been replaced since I bought it (@129k miles)
All other time sensitive parts (I.e. timing belt, water pump) have been replaced)
Burns almost no oil
No leaks, fluids OK

Basically I am thinking this has to be either a bearing on the output shaft of the engine or the input shaft of the tranny. Its also possible its a badly worn clutch/flywheel that's experiencing resonance at that particular engine speed. Let me know what you think.

Thanks in advance.
