Quizplus · Accepted Answer

Sodium-filled valves are used in some high-performance engines to help dissipate heat from the valve to the valve guide and ultimately to the engine coolant. Cutting them open is dangerous because the sodium inside, which is kept in a metallic state, can react violently if exposed to air or moisture, potentially causing injury or damage.
