At JSI Auto Solutions in Los Angeles, near Inglewood, our skilled technicians service and rebuild engine valves — including the valve head, stem, spring, and seat — to ensure proper sealing, smooth airflow, and maximum engine efficiency.

• Valve Head – seals against the valve seat to open or close airflow.

• Valve Stem – guides the valve’s up-and-down motion.

• Valve Spring – returns the valve to its closed position after each cycle.

• Valve Seat – provides a sealing surface for the valve head.
