It isn't the tires being roasted at all times is it? Just kidding. You best bet is to use a long screw driver and see if you can pinpoint the noise and where it is coming from.

That bearing looks great! I have seen some with the brass showing and they still work fine! I would look elsewhere. Are you sure it wasn't something like a small vacuum leak wistling, or maybe something in the tranny?

EDIT

That cam bearing lookes worn to me..worn evenly. is there a difference between the lip and the body of the bearing?

Do you have a magnetic drain plug? metal shaving?
