Default Rattling Noise near Harmonic Balancer

Ok, so I had a problem start yesterday where I started hearing a rattling, first thought it was the converter (planning on replacing that anyways) but when it got worse today, investigated, and the best I can come up with is that it'* either the Harmonic Balancer or the Timing Chain.
I've read some other threads to test out other theories first, I removed the drive belt to see if the noise would go away, but it didn't. So I'm really thinking that it'* the timing chain.
If anyone has any other possible symptoms, I'm open to anything.
I've never dealt with this before. And one thing I noticed was the bolt on the balancer is a bit rusted, any ideas how to get it off without stripping it?
Please, any advice or insight would be greatly appreciated.

Not sure what you are hearing, if you were able to get an audi clip of it, upload it somewhere like youtube, then post it, that would help, but I know that is not always possible.
Somebody else may have some ideas for you..
As for the rusted bolt, get something like this, and spray it, then let it soak a while, spray it again and give it a go, if it does not come easily spray and wait a little longer.

Unless the bolt head is rusted to the point where you can't get a socket to take hold, surface rust will not cause the threads to strip on such a large diameter bolt.

If you live near a Harbor Freight invest $10 in a mechanic'* stethoscope. It can be very helpful with issues like the one you are having.
