Inlet & Exhaust Valve Guide
Mitsubishi FUSO®

The Inlet & Exhaust Valve Guide, also known as the valve sleeve, is an engine component that guides the movement of the intake and exhaust valves. It is typically made of bronze or cast iron and is designed to withstand high temperatures and pressure. The valve guide is installed into the cylinder head and provides a precise path for the valve stem to move up and down. It also helps to maintain proper alignment between the valve stem and the valve seat, ensuring efficient engine performance. Over time, the valve guide can wear out due to constant friction with the valve stem, which may cause oil consumption or engine misfires. Therefore, it is important to regularly inspect and replace worn out valve guides to maintain optimal engine performance.
