Re: OIL FILTER MYSTERY

There should be one or two very small holes--maybe 1/16" or so on the side of the center pipe. On most postwar filters Packard used, oil enters side port, passes thru the filter and exits the center pipe via the hole(s) and back to engine. They might be closed with the sludge but may be high enough to still be open.

Am surprised being a partial flow filter with oil free to go elsewhere in the engine if that path was blocked that there was enough pressure to do all that leaking just because of a clogged outlet. If the lid wasn't loose, there may still be an issue and I'd look very carefully at gasket fit and mating surfaces. Make sure the lid or rim isn't distorted.
