What is typically the result of insufficient valve margin width?

Insufficient valve margin width typically leads to a higher risk of burning or warping. The valve margin is the area of material between the edge of the valve head and the seat of the valve. When this margin is too narrow, it compromises the valve's ability to withstand high temperatures and pressures during engine operation.

This can result in the valve not being able to dissipate heat effectively, which can lead to overheating. As a consequence, the valve may warp or suffer burn damage due to the extreme conditions it faces, ultimately affecting engine performance and reliability. Thus, maintaining adequate valve margin width is critical for ensuring the longevity and proper functioning of engine components.
