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

Replacing the engine does not prevent a car from passing the annual inspection, but it is necessary to first complete the modification registration at the vehicle management office; otherwise, the inspection cannot be passed. According to the motor vehicle registration regulations, if a registered motor vehicle undergoes any of the following changes, the owner must apply for modification registration at the local vehicle management office: changing the body color or replacing the engine. If the engine is replaced without completing the modification registration at the vehicle management office, the vehicle will not pass the annual inspection. Documents required for engine replacement modification registration include: the vehicle license, vehicle registration certificate, motor vehicle modification registration application form, motor vehicle registration business process record, owner's identity proof, engine origin certificate, safety technical inspection certificate, and criminal inspection certificate.
Last year, my car's engine had issues, so I spent some money replacing it with a new one. After the replacement, I had to promptly visit the DMV to complete the change registration procedure, bringing along the purchase invoice and maintenance records for them to verify if the new engine model and displacement met the original vehicle standards. Once they updated the engine number on the vehicle registration certificate, I went for the annual inspection and passed smoothly. The whole process wasn’t as troublesome as I imagined, but the reporting step couldn’t be skipped. The emissions test also went fine. When choosing an engine, pay attention to matching it with your car model—don’t go for a cheaper, higher-displacement one just to save money, or you might fail the inspection and even face penalties. I recommend consulting your local DMV rules before replacing the engine to ensure everything is compliant. This way, you can drive with peace of mind later and avoid unnecessary hassles. Remember, timely paperwork is key.
I'm in the auto repair industry and have dealt with many cases of engine replacements. A car with a replaced engine can definitely pass the annual inspection as long as the proper procedures are followed. You need to first apply for modification at the vehicle management office, submitting the new engine's certification and installation documents, ensuring the model and emissions match the original vehicle. During the inspection, they focus on checking the engine number, emission levels, and also test noise and safety performance. If an non-compliant engine is installed, such as one with excessive emissions or illegal modifications, the inspection will definitely fail and may even result in fines. I've handled several cases where owners didn't declare the replacement and got stuck during inspection. My advice is to have a professional repair shop evaluate compatibility before replacement to ensure the engine matches the vehicle model. This way, passing inspection in one go is no problem, and future maintenance will be easier. Don't gamble with luck—doing things properly is the safest approach.
