Does the Camshaft Need Replacing?

Whether a camshaft needs replacing depends on the extent of its wear, deformation, or damage. Camshafts are subjected to high temperatures, high pressures, and friction during long-term operation. If issues such as flattened cams, scored journals, or fractures occur, valve timing will be misaligned, directly affecting engine performance. Minor wear can sometimes be addressed through polishing or repair. However, severe damage can lead to abnormal valve operation, reduced power, increased fuel consumption, and even damage to other components. In such cases, replacing the camshaft is the most reliable solution. Therefore, if you notice abnormal engine noise, an increase in metal shavings, or power loss, you should promptly inspect the condition of the camshaft and comprehensively assess whether replacement is necessary to avoid greater damage.
