An overhauled engine is an engine which has been removed, disassembled (torn down), cleaned, inspected, repaired as necessary and tested using factory service manual approved procedures. The procedure generally involves honing, new piston rings, bearings, gaskets, oil seals. When done by a competent engine builder the engine will perform as new. The engine may be overhauled to ‘new limits’ or ‘service limits’, or a combination of the two using used parts, new original equipment manufacturer (OEM) parts, or new aftermarket parts. The engine’s previous operating history is maintained and it is returned with zero hours since major overhaul.
Many times aftermarket part manufacturers are the OEM part suppliers to major engine manufacturers. A top overhaul only covers the replacement of components inside the cylinder head without removing the engine from the vehicle, such as valve and rocker arm replacement. It may or may not include a valve job. A major overhaul however covers the whole engine assembly, which requires the engine to be removed from the vehicle and transferred to an engine stand. An overhauled engine refers to a major overhaul. By comparison, a major overhaul costs more than a top overhaul.
