The only way the oil could get out the bottom is if the canister has the plug and someone removed it OR the outlet fitting is missing. If you have a canister with the threaded hole on the bottom (slightly offset from center) you'll need a 1/8" NPT plug. If you have a hole directly center on the bottom that's the outlet. The thread is the same as the plug. All of that is for the Fram canister. Other models may be slightly different.

I have had to re-seat the center stand pipe and its not hard.. get a piece of pipe, fit it over the center pipe and put the filter on a metal plate... tap it till its firmly in place. You could also silver solder it... but after 3 years it has not leaked.
There should also be a fiber/copper washer under the lid bolt. That is also a place for oil to leak. Most of the lids that leak will have pits on the bottle of the lid from old cork gaskets that have rusted the lid. You can use RTV to fill in the pits, or use a softer rubber to get a better seal.

Oil goes into the tube, through the filter and out to the canister. Then back to the engine. "O" rimgs in the center of the filter are the "seals".

The oil actually enters at the side fitting, passes through the filter to the inside then into the stand pipe and back to the engine. I just changed the oil & filter in my '38 or I'd be able to take a pic of a filter to illustrate it. I do have a scan of Fram installation instructions that shows the routing of the oil lines. <CLICK>
