An engine overhaul is a comprehensive repair process that involves disassembling, inspecting, and rebuilding your engine. The engine is carefully removed from the vehicle, disassembled, and each component is thoroughly inspected for wear, damage, or defects. Worn or damaged parts are replaced with new or remanufactured components, and the engine block, crankshaft, connecting rods, and cylinder head are often cleaned, machined, or resurfaced to ensure proper fit and function. The rebuilt engine is then tested to ensure it runs smoothly before being reinstalled in the vehicle.
