Can an Overhauled Engine Carry Passengers?

[Joanna]

An overhauled engine can carry passengers, but to extend the engine's lifespan, it is advisable to minimize the load and avoid long-distance driving. Engine Overhaul: An engine overhaul typically involves replacing damaged or severely worn components with new parts. Since the labor cost for an engine overhaul is very high, many users opt to have the repair done at a repair shop, often using aftermarket parts or even used components. Engines reassembled in this manner may see a significant reduction in performance and reliability. Conditions Requiring an Engine Overhaul: Low power: The engine's maximum power should not fall below 90% of the originally designed value, as measured by a dynamometer according to relevant regulations. High fuel consumption: The engine's minimum fuel consumption rate should not exceed the originally designed requirements, calculated using fuel consumption metrics. Low torque: The engine's maximum torque should not fall below 90% of the originally designed value, as checked by a dynamometer according to relevant regulations. Severe loss of operational capability also warrants an overhaul.
