Re: water pump sealing
The gaskets are there to provide the seal, and don't normally require any extra adhesive. If your leak is excessive, it may explain why your impellers are short lived, and the lack of water at your tell-tale.<br /><br />Have you removed and inspected all of the water pump seals and gaskets? Checked water pump housing for cracks? If not, it would be a good idea given your recent issues.<br /><br />I'm not familar with motors from the 60's, and not sure if they are arranged differently than the newer ones.
