Nice to see that the issue has been resolved, but I just wanted to drop in another possible solution for the next person who rolls through here While Google searching, trying to figure out what's wrong with their car:
You said initially all you had to go on was it seemed like a spinning sound. Last Summer, I had a mystery sound come up on the car that I thought was valves or something else, but it would go away every time I accelerated. I just couldn't figure it out. I even had it in a shop for another reason and turned the engine on for the guy and he was stumped, too.
No harm done in re-adjusting the valves, so I took it over to a friend and we got to work. Got them adjusted real nice, and the sound was still there. So now what?
He started working on the Belt, I forget why, and we came upon the issue: the fan was loose. It was wobbling so bad it was hitting on the underside of the shroud, making the noise. Apparently the bolts had not been tightened down completely the last time the top was taken off, and three of them were almost ready to come all the way out. We tightened them down, and it has not been an issue again.
