Can a car pass the annual inspection after an engine replacement?

After replacing the engine, the vehicle needs to undergo a modification registration. Once the modification registration is completed, the car can proceed with the normal inspection. Below is extended information regarding motor vehicle registration: 1. Application for modification registration must be submitted to the local vehicle management office in the following cases: (1) Changing the body color; (2) Replacing the engine; (3) Replacing the body or frame; (4) Replacing the entire vehicle due to quality issues; (5) Changing the use nature of the vehicle, such as converting a commercial vehicle to a non-commercial vehicle or vice versa; (6) The vehicle owner's residence moves out of or into the jurisdiction of the vehicle management office. 2. Motor vehicle registration regulations: Vehicle owners can apply for an inspection compliance mark at the local vehicle management office up to three months before the expiration of the current inspection period. Before applying, the vehicle owner must resolve all traffic violations and accidents related to the vehicle. When applying, the owner must fill out an application form and submit the vehicle's license, compulsory traffic accident liability insurance certificate, vehicle and vessel tax payment or exemption proof, and motor vehicle safety technical inspection compliance certificate. The vehicle management office should confirm the vehicle's identity, review the submitted documents, and issue the inspection compliance mark within one day of receiving the application.
With years of experience in car repairs, I've seen many owners replace their engines. The key is that the new engine must match the original car's parameters, such as displacement and model, and meet the current China 6 emission standards to pass the annual exhaust test. After replacement, it's essential to update the engine information on the vehicle registration at the DMV; otherwise, discrepancies found during the annual inspection will result in disqualification, wasting all your effort. Also, pay attention to proper safety debugging—don't cut corners by going to small workshops. Improper engine installation can lead to issues like excessive vibration, increasing long-term costs. It's best to have the entire process handled by professional technicians who are familiar with the procedures, ensuring no emission violations or unregistered modifications, saving you a lot of hassle.
