Others will have more knowledge about these specific motors, but if the impeller does have a crack, then I would say that yes that would cause a leak. Buy all new seals, new impeller, etc, and replaced them. If you can figure out what caused the cracking, and make sure the water pump housing is in good shape as well before using it with new seals and impeller. Should fix the weep hole leak unless other issues are there.
