What can occur if valves are not properly maintained?

If valves are not properly maintained, potential engine failure can occur due to several reasons related to their crucial functions. Valves are responsible for regulating the flow of air and fuel into the engine’s combustion chamber and the expulsion of exhaust gases. If they are worn, misaligned, or not sealing properly, it can lead to problems such as poor combustion, loss of compression, or overheating.

These issues may manifest in various ways, including a decrease in engine performance, increased emissions, or even catastrophic engine damage. For instance, if an intake valve is not opening at the correct time, the engine may not receive the necessary air and fuel mixture, leading to poor power output and efficiency. Similarly, if the exhaust valves are not functioning correctly, it can result in back pressure that stresses other engine components.

To maintain optimal engine health and performance, regular maintenance of valves is essential, as neglecting this aspect can ultimately lead to severe engine failure, requiring significant repairs or replacements.
