I am so sick and tired of water pumps that leak! Just about to fire up an engine that I rebuilt myself (just rings, lap in valves adjust all clearances, rebuilt dizzy, carb and water pump). I filled with 50/50 yesterday morning and saw a very slow drip at the pump. But from every thing I can tell it seems to be coming from the pressed in bushing and the pump body. The drip only was about 1/3 cup in around 24 hours, and it comes right down the face of the casting where the bushing comes through. No leak on the shaft to pack nut, and if it was coming out around the threads of the pack nut I would think it would drip off the end of the pack nut and not travel along the threads to the casting face.
Do you think I can either add a bead of RTV as a fillet along where I think this is leaking? Or is anyone a proponent of the leak stop additives to the coolant?
I have already decided that whether I can afford it or not I am going to get one of the sealed bearing pumps for my Roadster, but was going to leave this Town Sedan with the one I rebuilt.
