Block damaged by metal waterpump impeller
This is what I found when I popped the boy's waterpump off today.

The bottom edge is smooth - not surprising since the impeller was pulled up by the belt - the upper edge has a noticeable edge not unlike a worn disk rotor
Here's a close up.

What kind of water pump was it?

I think there's a Dwayne write-up of the repair as well.

It's an old factory pump (unless it's counterfeit) since there's a Porsche part number cast into it. In the recess above the pulley there should be a 2 digit date stamp embossed in the metal. How old?

I looked at Dwayne's and his damage looks much worse than mine.

Check the wear with a new pump and clay?
Doesn't look bad enough (from here) to fix. Probably won't affect cooling potential.
Seen similar after removing a newer pump which was installed over previous damage.

+1. I doesn't look like much damage at all. Maybe 1mm at the top and nothing at the bottom.
If that's true, then just get a new pump and go.
The old pump was likely a rebuilt.
