Bought a water pump off rockauto closeout, cast iron of course for the particular engine, and here's what showed up:
Surface rust inside as you can best see by the impeller, and on the mating surface, but inside the passages as well. What's visible of the shaft inside looks clean.
My concern is both whether system contamination would be an ongoing issue, and, long term gasket seal issues even if that rust is attacked with a scotchbrite and such before adding some rtv to the felt style seal.
It's not an off-the-shelf part for the local stores (useless) who wouldn't give me a firm arrival date for the 'special order we don't keep in stock'...
Thoughts?
