The answer is yes. When an engine is disassembled the engine is assigned a work order number that follows the engine throughout its time at our facility. All parts are identified using a metal with the work order stamped into the tag. The tags are only removed when the assembling mechanic begins the build process. Many of the parts as serialized, cases, crankshaft, and cams can provide traceability by serial number. These can be verified by the engine log book or visual inspection. Although logistics does not always make it possible, you are welcome to visit our facility and watch your engine being inspected, built and test ran.
