Re: '54 oil filtration question...

Good question. Packards used a by-pass oil filtration system as opposed to a full-flow system. The by-pass allows only a small amount of oil flow to go through the filter. This is necessary to preserve pressure and flow to the other parts of the engine. While the filter traps some of the impurities much of it is captured by settling to the bottom of the housing. Ever notice how much gunk is in the bottom when servicing the filter? By-pass does work, but does it differently than the full-flow types. Packard also recommended removing and cleaning the oil pan and pump pick-up screen once per year.
