Re: 1934 Packard Replacement Oil Filter

Yes, I'm familiar with the 1934 Eight full pressure oiling and filter system, and the Burr Ripley filter kit. The factory oil pressure relief valve assembly provides for the filter.

The original Purolater L6 filter did not itself contain a check relief valve. The Packard engineers that designed the new for 1934 full flow oiling and filter system anticipated that a filter might plug or restrict flow and built protection into the oiling system. The check valve to redirect the oil flow directly to the galleries should the filter become plugged or restricted is the second of the two relief valves in your oil pressure relief valve assembly on the driver side of the engine block. A second relief valve in the filter for the same purpose is not required.

On your relief valve assembly, the horizontally oriented valve under the large acorn-shaped nut at the rear is for pump over pressure relief; the vertically oriented valve under the smaller hex cap on the top of the unit is the one for the filter.
