Can a re-stamped engine number be identified?

[DeElizabeth]

It can be identified. Re-stamping requires grinding off the previous number, which can be seen upon close inspection. The specific details about engine numbers are as follows: 1. Front section: Includes product series code, generation symbol, and regional/enterprise code. Manufacturers may choose appropriate letters as needed, but these must be approved and recorded by the industry standard regulatory body. 2. Middle section: Consists of cylinder count symbol, cylinder arrangement symbol, stroke symbol, and cylinder diameter symbol. 3. Rear section: Composed of structural feature symbol and usage feature symbol. 4. Tail section: Differentiation symbol. When differentiation is needed due to improvements or other reasons within the same product series, manufacturers may select appropriate symbols. The rear and tail sections may be separated by a "-".
