What is the primary purpose of an engine overhaul?

To enhance engine performance

Inspect, repair, and replace worn engine parts

The primary purpose of an engine overhaul is to inspect, repair, and replace worn engine parts. Over time, engines experience wear and tear from normal operation, which can lead to loss of performance, efficiency, and safety. An overhaul involves a thorough examination of all engine components, including critical parts like pistons, bearings, and valves, to assess their condition. If any components are found to be worn beyond acceptable limits, they are either repaired or replaced to restore the engine to a condition that meets or exceeds safety and performance standards.

While enhancing engine performance, increasing fuel efficiency, and modifying engine design are important considerations in specific contexts, the main goal of an overhaul is to ensure the engine functions reliably and safely by addressing its mechanical integrity through careful inspection and maintenance.
