Thank you.

you cannot get water inside metal

The Germans put sodium in exhaust valves. Close?

sodium is a metal

[oldmako69]

Thought it was a mineral?

"These sodium filled valves follow the same cooling principal as a human's ability to sweat. The solid sodium in the valve has a very low melting point (97.72C) and high boiling point (883C). This means the liquid sodium that condenses at the bottom of the valve near the combustion chamber boils off to the top of the valve when properly heated. This process of evaporation dissipates heat from the combustion process cooling the engine.

"The sodium at the top of the valve eventually condenses back into a liquid forming a sort of rain cycle right in the valve of your own engine."

Either way, water in the piston sounds bad. Even if it's only water in the cyliinder.

Sodium is an element that is a member of the alkali metal group with a symbol Na. It is physically silver colored and is a soft metal of low density. Pure sodium is not found naturally on earth because it is a highly reactive metal.

Very interesting. Is this heat exchange system used elsewhere?
When I’ve seen pure sodium it looked yellow and not metallic at all. This and it’s reactive ness (put it in water and watch) makes many people believe it is not a metal. To be a meta it has to have other characteristics like malleability and ductility, but I don’t know how you would test that easily. Potassium is also similar and a metal.

It might pay to be a bit more descriptive, like what motor, 2 stroke, 4 stroke 15HP, 150HP, exact model will be nice, I guess you have water in a cylinder? if that's the case, then it might be simple, or disaster.

[robert graham]

Maybe he meant water in the cylinder????
