Please brain storm on this. Doesn’t the top of the oil pump assembly have a built in pressure relief by way of the spring that holds the oil pump/distributor assembly together by spring pressure. I recall that if oil pressure exceeds the spring pressure it will compress the spring a small amount and let oil flow into the valve chamber. This would be a safety mechanism if the oil passage going to the front oil chamber is blocked. Remember in 1929 oil was not what it is now and Ford engineers anticipated this and made this bypass, remember at that time the reputation of the durability car was a big selling point and at this point in history people had a hard time feeding their children let alone buying oil in the Great Depression. I put a Mikes filter on my 29 coupe but I am taking it off, I believe that during initial startup of the engine the filter set starves the valve chamber of oil for enough time to cause esscess wear over time. The oil system was designed as a low pressure splash and drain system, I think Fords engineers were a lot smarter than most of us including me. Really oil is cheap, we don’t drive them that much(use synthetic), with most of us if we can afford and love our machine we can change oil every 500 miles. I do not recommend an oil filter, right Des?
