Hi,
The fresh water pump on my universal diesel engine has started to leak ever so slightly through the weep hole, indicating that the seals are failing. I spoke with a good local mechanic who said its more expensive to rebuild than to replace, so I've ordered a new pump. It comes with a paper gasket, but I'm thinking that paper gaskets may not last the life of the pump, so I'm thinking to use a Permatex gasket maker/sealant. I found one that is suggested for everything including water pumps, can tolerate high heat and is ok to use with auto fluids.
I have had conflicting advice with some saying to still use the paper gasket plus the sealant, others advising to do one or the other but not both together. An additional factor is that when the current pump was installed eight years ago, the mechanic broke two of the ten studs that hold it onto the engine block. He advised against trying to drill them out of the aluminum block, and simply left them out, using only eight. The pump has not leaked, so that worked. I don't know if that should affect my decision to use the paper gasket, the sealant, or both together.
Any thoughts or advice on getting a good seal for my waterpump?
