I'm building a 1947 59A engine and have installed new water pumps made for this block. I'm confused about what to do about pump lubrication. The instruction book I'm using is unclear whether the oil ports on the block and pumps should be blocked. If they aren't blocked with pipe plugs do I need an oil line to connect the outlet on the block to the water pump?

do the pumps have bushing or sealed bearing ? are they SKIP'S pumps ? SEALED BEARING DO NOT REQUIRE the oil supply,and will block off the oil supply, were the bushing NEED oil lube, so the block oil holes have to be clear, and need to work, you can clean these out with a wire, usually oil drips out of them., DO NOT USE SILCONE SEALERS,they will clog up the oil holes,and will also end up in the cooling system, the old fashion INDIAN HEAD gasket sealer is the best, or PERMATEX, NO 1 37RAGTOPMAN an KEEP on FORDIN,,!!!!!!!!!!

The original style pumps are lubricated by gravity. There is a passage from the timing gear cover leading to each pump. The sealed bearing type is lubricated for life, and needs no further oiling. I agree that using silicone sealer on pumps is not a good practice. Silicone has its place, but too many users slather it on, instead of making a small bead around the edges of the part. Some newer vehicles require special silicone compounds to form a gasket, but that stuff doesn't dissolve, and can cause major damage if it gets loose inside the engine. When installing flathead water pumps, we use a varnish type sealer on the gaskets. If you don't have any, a very thin film of grease will work, or you can install them dry, if both surfaces are flat and clean.
