I was discussing the repair of a 2.1L case with some damage under the
water pump with a couple of mechanics. After studying the damage I am not
so sure it is a problem. The water pump does not depend on any clearance
from the engine case. The impeller's blades face the body of the water
pump so wear in the engine case should not affect the pressure. The area
behind the pump has only one outlet so I can not see how loss of material
in this chamber could be a problem.
       Please pick up a water pump and inspect it carefully before
responding.
