Re: 1940 110 Touring Sedan Irregular Oil Pressure

Thank you TxGoat for the detailed response. By oil pressure limiter are you referring to the pressure relief spring? I opened the nut on the pump housing / pressure relief valve and the spring came out along with a metal sleeve. Not sure if the sleeve should be pressed into the housing. It basically fell out with the spring.

I think I do have a hint of gasoline or combustion odor in the oil. I figured it might be the result of a worn, stuck or broken ring but never gave thought to the fuel pump. I don’t have a vacuum hose attached to the fuel pump so probably not a vacuum assist for the wipers. The pump is mounted to the engine directly above the oil pan. Can the pump leak fuel into the engine?
