Georgios,

Sorry for the previous empty message....%&*$# touchpad... anyway

I had similar damage to my case after ignoring the rattling noise
coming from the pump. The  groove my impellers wore were deeper into
the case metal. I replaced the pump without addressing the damaged
case. That was 130k miles ago with no pump problems since. The temp
gauge sits on the lower edge of the warning light so it seems to be
doing it's job as intended. Of course the usual YMMV disclaimers
apply.. Good luck with yours.

John
