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

[DelReagan]

It is not acceptable to stamp the same engine number when replacing an engine. If a new engine is installed with a different engine number, the vehicle registration must be updated accordingly with the new engine number. Below is an introduction to the engine stamping number: 1. Positions 1-3 (WMI): World Manufacturer Identifier, indicating the manufacturer of the vehicle; 2. Positions 4-8 (VDS): Represent vehicle characteristics, including type, series, body style, engine type, and restraint system type; 3. Position 9: Check digit, used to prevent input errors through a specific algorithm; 4. Position 10: Model year, which is the year designated by the manufacturer (Model Year) and may not necessarily match the actual production year, though the difference is typically no more than one year; 5. Position 11: Indicates the assembly plant; 6. Positions 12-17: Sequential number. Generally, vehicle recalls target a specific range of sequential numbers, meaning a particular batch of vehicles.
