Is Replacing Pistons Considered an Engine Overhaul?

[McChase]

Replacing pistons is not considered an engine overhaul. Automobile Overhaul: An automobile overhaul refers to the comprehensive or near-comprehensive restoration of a vehicle's technical performance, typically performed after a new car or a previously overhauled vehicle has been driven a certain mileage or period of time. This process involves diagnosis, technical evaluation, and the repair or replacement of automotive components. Parts Typically Replaced During an Engine Overhaul: Valve stem seals, a complete set of intake and exhaust valves, a set of piston rings, a set of cylinder liners (4 in total), two thrust washers, connecting rod bearings and main bearings, 4 pistons. The cooling system components generally include the water pump (if the impeller is corroded or the water seal shows signs of leakage), upper and lower radiator hoses, the main metal coolant pipe, the small circulation rubber hose, and the throttle body coolant hose (must be replaced if showing signs of aging or shrinkage). The fuel system components typically include the upper and lower fuel injector seals and the fuel filter. The ignition system components generally involve inspecting the high-voltage wires for shrinkage or leakage (replace if necessary), spark plugs. The intake system components usually include the air filter.
