I cranked up my old 1947 Oldsmobile Straight Eight today and drove it about thirty miles or so;noticed a lot more fumes than I remembered.I sold this car and bought it back; the person I sold it to had the fuel pump rebuilt and I think that the fuel pump is putting fuel into the crankcase as well as letting oil leak out at the pump; I think I will rempve the pump and use an electric fuel pump installed close to the tank and I would also like to add a Positive Crankcase Ventilation set-up! Any good ideas on which type of valve to use etc. any websites on this? Thanks for helping the old man out! "Leroy"
