Cleaned up another water pump housing to have it prepped and built up ready to swap out and sure enough it is probably junk like all the others The hose nipples on this one were actually very clean, the flange for the pump seal was wrecked with one spot completely eaten through from inside to outside. Going to sandblast this one tomorrow and see how bad the rest of it is. Some rtv will most likely make it work fine if there are no cracks and the pitting does not go too deep. But why do these things just crumble and corrode so badly ?? some really low grade pot metal aluminum ? sure the pumps get a little crusty on the outside but they dont get eaten away like the housings do.
