I'm not sure that sodium reaches a liquid state at the temperatures encountered in even a turbo-charged internal combustion engine. Anyone got another theory?

As the valve opens and closes the liquid sodium moves inside the valve,
taking the heat away from the tip and transfering it to the well cooled
stem. Liquid sodium is an excellent heat conductor - it is used on some
nuclear sumbarines for cooling reactors.
