Can the original engine number be stamped when replacing an engine?

[MarianaDella]

No. According to legal requirements, replacing an engine requires applying for a change registration at the local vehicle management office. The vehicle owner should apply for a change registration within ten days after the replacement. Circumstances requiring change registration: Changing the body color; replacing the engine; replacing the body or frame; replacing the entire vehicle due to quality issues; changing the use nature from commercial to non-commercial or vice versa; the owner's residence moving in or out of the jurisdiction of the vehicle management office. Required documents: The owner's original ID card; a safety inspection certificate issued by the inspection station; the original vehicle registration certificate and driving license; the replacement engine's qualification certificate, invoice, and import documents.
