What cause a camshaft to go bad?

A camshaft can go bad due to several factors, including wear and tear from prolonged use, lack of proper lubrication, and exposure to contaminants. Overheating, often caused by engine problems or insufficient coolant, can also lead to camshaft failure. Additionally, improper installation or alignment can result in premature wear or damage. Regular maintenance and timely oil changes can help prevent camshaft issues.
