hi guys I have a stock 41 ford coupe with 20,000 miles on the Flathead stock water pumps which I don’t know how long they have been there. Recently found some oil under the radiator cap about the size of a quarter after I drive it. I have a new rad about 2 years old . I drained the rad and found no oil in the water. I also have some play in the pump head where the belt goes, also oil accumulation on the motor mounts and arm on the mount. All on the drives side. Nothing on the passenger side. No loss of water from rad, no water in the oil , no combustion gases in rad per test. No overheating at all, no smoke or water out the back.Now I was told that the seals on these pumps wear out and the lubrication of these bushings is from the engine oil. This wear could put oil in the rad. I want to get them rebuilt by skip haney. Had this happened to anyone else. ?
