The circumstances under which engine numbers can be altered and the restoration methods are as follows: Circumstances allowing engine number alteration: The engine number becomes illegible or damaged due to wear, corrosion, accidents, etc.; The engine needs replacement due to original engine quality issues; If the engine number was altered during vehicle theft, the owner can apply for record filing at the vehicle registration authority. Engine number restoration methods: If the frame number, engine number, or vehicle identification number has been altered - when the altered engine number is deeply engraved and cannot be restored, but if the alteration isn't deep or only involves erasing the original number, you can clean the metal surface with sandpaper, then apply diluted sulfuric acid with a cotton swab to restore the number.
