Yes if the valve is leaking. But in general the answer is no.
One way valves are used on any tires. It lets you air up the tire and the valve keeps it from leaking air back out. If you want to check if your vale is leaking, just pour a little water on to the valve. You will see bubbles comming form the valve if it is leaking. If no bubbles, there is no leak.

sounds like pressure relief valve if replacing the valve doesn't stop the leaking you may have to much pressure in your cooling system mainly a Head Gasket leak.
The valve in a tire valve stem is a Schrader valve, it is a one way valve that is spring loaded shut. If air is leaking out, it is usually dirty and the dirty is holding it open preventing it from sealing/ or never reinstalled properly during last service. There is a tool to remove the valve, for quick deflating/servicing. Use soapy water or cleaner like windex/fantastic to check if it's leaking. If it is it will foam/bubble up.
Reseal or replace the valve.
Have it rebuilt and new seals put in.

The oil leak is coming from the valve cover gasket and leaking onto the exhaust manifold, the rubber valve cover gaskets get hard from the engine heat and start to leak, you will have to replace the rubber valve cover gaskets to stop the oil leak
No, it should not leak freon because it is supposed to be a sealed unit.
It cannot smoke out of the spark plug. It can however be leaking oil around the spark plug area thus causing it to smoke. The problem is the valve cover is leaking. Try tightening the valve cover bolts slightly. If that does not stop the leak, replace the valve cover gasket.
