>It looks like our beloved 85 Westy will be needing a new water pump.

The PO had replaced the one in my 85, but when I bought it and had my
mechanic check it over, he said it was leaking.  He took it off and
found the gasket slightly twisted.  He said that it was a common
problem because the thing was so durned hard to get at.  So be
careful to get the gasket on straight and flat.
