Two items: The valve stem will only leak fluid if the fluid is above the location of the stem. soap will not work to indicate leak. The valves have two parts, one that is used to admit air only, and one for liquid. They can be disassembled. Use a commercial electronic (not magnetic) stud finder to find the level of fluid in the tire. Jack the axle till all pressure is off the ground. Rotate the tire till the stem is well above the level of liquid. Let out all air pressure (gently enough not to squirt fluid if the tire is almost at max liquid). Remove both components of valve and replace them. Look (with a hand lense/magnifier) at the mating surfaces in the stem to see if they are corroded. If they are, it may be new tube time. if a little ugly, light 1000 grit Si-carbide paper can be used sparingly to polish mating areas. install new core/valve snugly, and then clean up the surrounding rim. Wipe this area with laquer thinner (unless painted with a disolvable paint, in which case use soap/water and let dry). Spray this area with a spray can product called urethane clear coat for clear coating repair paint jobs, from a commercial autobody supplier. if you don't like the glossy look, use 000 steel wool to reduce the shine to look like it should.
Good luck, I have fixed three and replaced the tube in two. that were leaking/rusting.
