I have a 51 ford v8 pickup. How does the oil filter work? Is there some kind of plug that prevents the oil from draining down into the engine. It seems to me the way it should work is to have pressurized oil fed in from the top, which then goes thru the filter and exits thru the center pipe by being forced thru tiny holes. Then the oil , it seems to me, proceeds down thru the center pipe back into the engine. Recently, I have opened the filter cap and the oil has drained out. When I first changed the oil I had to scoop out the oil. Am I missing a part?

Peter, the oil filter is a bypass system, having a small diameter oil return hole to prevent low engine oil pressure. Do not try to enlarge that hole. Most guys use a suction device such as a turkey baster to remove the oil remaining in the canister before installing the new filter. There was even a tool on the market designed specifically for the purpose, made by FRAM. No, don't blame Ford for the design of the canister filter, Fords filter prior to the FRAM canister was a horizontal mounted self contained disposable filter.

I believe that on '48-'50 models they used a different brass intake fitting with a "small diameter hole", but on '51-'53 models, the "small diameter hole" is in the brass intake fitting, part number 1BA-6073, on the truck filter that the oil pressure sending unit screws into. If you don't have this fitting, your oil pressure will be low. The oil from the filter is free to discharge into the crankcase. Only about 25% of the oil goes through the by-pass filter. Richard
