the generator has a place to put oil, the distributer has a place to oil, the starter, and the water pump ,on either side of the pump housing is a brass cap, when screwed off looks like a zerk fiting but i think oil goes in the fittings with a needle oiler. question is : what kind of oil.
In the 1929 models, you removed the caps on the water pump and placed a special water pump grease in there. As the grease level goes down you simply turn the cap to add a little more pressure and take up the slack. When the grease comes into contact with hot water as it will, the grease will dissolve into the water ant not clog the radiator. You can get the water pump grease from Restoration Supply in southern California, the address is on the Tech page.
