Uh, yeah. 50K. Those belts are screaming for a change.
If you've got a long extension, or other solid piece of metal, start the car and hold it against the valve cover with the upper end against your ear. Listen carefully for clicking, clattering or tapping sounds.
Next hold it against the alternator. Does the sound you heard get louder?
Next, move it as close to the water pump as you can get it and listen.
One of these will have a sound that duplicates what you're hearing through the air. It will identify the offending component.
5w30 is perfect.
Please come back and let us know what you find.
