What can be a consequence of not replacing worn components in an engine?

  1. Improved overall performance of the engine

  2. Decreased engine efficiency and potential failure

  3. Increased fuel savings

  4. Extended lifespan of the engine

The correct answer is: Decreased engine efficiency and potential failure

Not replacing worn components in an engine can lead to decreased engine efficiency and potential failure. Worn parts, such as bearings, seals, or valves, can disrupt the optimal functioning of the engine by causing increased friction, reduced compression, or leaks. This degradation not only hinders the engine's performance but also makes it more susceptible to catastrophic failures. When an engine operates with worn components, the stress on the remaining parts often increases, potentially leading to a breakdown or complete failure that could require extensive repairs or lead to unsafe operating conditions. Regular replacement of components helps ensure that the engine maintains its efficiency and reliability, preventing issues that could arise from neglecting maintenance.
