Default Crank Sprocket Rub

I took a chance on a 2003 LE with 142k for $200 at anbandoned vehicle auction:

This is my first experience with a PT Cruiser.
I got it running and driving. But, found a significant coolant leak.

I tore down the front of the engine and found it leaking from the weep hole on the radiator:

I also found this~

Any idea what might have caused this?

I was concerned it might be a failing thrust bearing. But, I backed it off and there doesn't appear to be any abnormal endplay.

I'm currently waiting on a few parts/seals to come in. I'll be continuing re-assembly and hope to have it street worthy very soon.

EDIT: Weep hole leak on the WATER PUMP. Not the Radiator.

I hate it when forums don't allow you to edit your post.

When water pumps fail, that's how they fail. Just replace the pump. Should be good to go. Stay here and keep posting. Eventually they will give you editing privileges.

May have been some debris that got behind the gear and rubbed the cover.
Check crankshaft end play. If the thrust bearings are worn the crank may be moving to far and causing the contact. If OK just put it together. If not may have to dig deeper. If manual trans, could be a clutch issue.
End Play 0.0035 - 0.0094 inch Wear Limit 0.015 inch
