A cap is a good solution for motors without washers attached but if you need the port active the most likely reason for a leak only at the washer hose port is the wire cable working the slide valve is slightly mis adjusted.

For general leaks around or in the valve, the moving plastic portion of the slide valve has a flat spring under the sheet metal retainer which is supposed to keep it pushed tight to the machined slide surface on the pot metal motor cover. It is possible that spring is weak or since the sliding part of the valve is plastic, that could have warped. The machined surface on the valve or cover could be dirty or scratched too.

Any of those old motors could have dried out or just be tired and worn. A good many are probably long past due for a rebuild.
