leaky rear tire

I noticed my calcium filled rear tire of my 9N is leaking out the valve stem. I believe the valve is bad but I can't find the valves anywhere. The rear wheel is situated so the valve is at 12 oclock to minimize calcium loss for now.I would appreciate some suggestions for replacement sources.
