The water pump kit I have will need to be cleaned up a bit, and of course the gaskets are folded and hardened. Do you think they are still serviceable, or can I use them with RTV? Or is RTV itself sufficient?
IMO, if the gaskets will straighten without breaking and have not shrunk, they would be serviceable. If there is any question, new are relatively inexpensive and readily available from the vendors.
I think you will need the gaskets because of the small metal tabs attached to the distribution tube. Those are just bent over and lie on the flat block surface. The gasket, being thicker, provides a space for them. The service manual says coat the gaskets with gasket paste. Not really knowing what served as gasket paste back then, on the gaskets which came with the new repro water pumps from Kanter I smeared on a thin layer of Permatex's non hardening Form a Gasket #2A. I would think RTV would work also.
