Is it acceptable to stamp the same engine number when replacing an engine?

[VonDavid]

It is not permissible to stamp the same engine number when replacing an engine. Below is relevant information about engines: Concept: An engine (Engine) is a machine capable of converting other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. For example, an internal combustion engine typically converts chemical energy into mechanical energy. Classification: Internal combustion engines, external combustion engines (where fuel burns outside the engine), gas turbines, and jet engines.
