I guess the thing to watch is the water pump weep hole. If something bad
happened to the pump, the seal should fail. You might want to pull the right
timing cover to get a good look at it. If you really suspect the pump, I think
you can remove the bolt at the end of the damper and maybe get enough slack in
the t-belt to rotate the water pump to check the bearing.

I hope it is not that!!
