Valve guides are crucial components in internal combustion engines, designed to support and align the engine’s valves as they open and close. These cylindrical tubes are typically made from durable materials like steel or cast iron and are positioned within the cylinder head.

Valve guides ensure precise valve movement and maintain correct alignment, reducing wear and tear on both the valves and the seats. They also help manage the flow of lubrication to the valve stems, which is essential for reducing friction and extending the life of the engine. By providing stability and accuracy in valve operation.
