Engine seizure is considered a major overhaul, and it can only be addressed through a major overhaul. In the true sense, "engine seizure" should actually be written as "piston seizure." Simply put, it means the piston in the car's engine gets stuck with the cylinder liner. The cause of this failure is that the piston, due to a lack of oil cooling, overheats and expands, becoming stuck in the cylinder and unable to move. Relevant information about car engines is as follows: 1. Introduction: The car engine is the device that provides power to the vehicle, serving as the heart of the car. It determines the vehicle's power, fuel efficiency, stability, and environmental performance. Common gasoline and diesel engines are both types of reciprocating piston internal combustion engines. 2. Classification: Based on the power source, car engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrid types, among others.

That engine seizure incident, I've personally experienced it, and it absolutely counts as a major overhaul. Last year while driving on the highway, the engine suddenly lost power and started emitting blue smoke. After towing it to the repair shop, they found that cylinder overheating had caused damage to the cylinder walls. The mechanic said a major overhaul was necessary, and the reason was simple: engine seizure not only damages the cylinder block but can also affect internal components like pistons and crankshafts—it can't just be fixed with welding or partial repairs. A major overhaul means completely disassembling the engine, cleaning, measuring, and replacing key parts, such as possibly replacing the cylinder liner or piston assembly. It's time-consuming and labor-intensive, taking at least several weeks and costing several thousand dollars. Engine seizure often results from insufficient oil or cooling system failure—in my case, I forgot to change the oil, and the lesson was painful. If you notice abnormal noises or a drop in power while driving, stop immediately and check to avoid worsening the situation. Regular maintenance is key—don't skimp on small expenses and end up with big problems.

During my time working at the auto shop, engine seizures were quite common, and I could tell at a glance that a major overhaul was likely needed. A seizure usually involves cylinder damage, such as overheating or foreign objects causing scratches on the cylinder walls. During repairs, the engine must be disassembled, and pistons may need replacement or the cylinder surfaces may require honing. This isn't just a minor fix, as internal damage can trigger a chain reaction: oil passage blockages, shaft wear, etc., making a complete overhaul the safer option. The overhaul process includes lifting the engine, disassembling components, cleaning, and reassembly, which can be costly, and sometimes custom parts are required. Common causes include neglecting oil changes or cooling system issues. Regular checks of fluid levels and temperature gauges by the owner can prevent such problems. Once a seized engine is properly repaired, it's safe to drive again.

My husband's car had an engine blowout, and the entire engine was ruined at that time. The mechanic said it needed a complete overhaul because a bunch of internal parts were damaged, and it couldn't be fixed by just repairing a small section. A complete overhaul means disassembling the entire engine, reassembling it, and replacing parts, which takes weeks and costs a fortune. Engine blowouts are mostly caused by low oil levels or cooling system failures. That time, my husband forgot to maintain the car, and it broke down directly, requiring a tow truck to haul it away. Reminder to everyone: if your car shows problems like unusual noises, deal with them immediately. Don't let small issues become big ones. Fixing things early saves more in the long run.
