Should You Repair or Replace a Damaged Car Engine Block?
2 Answers
When the car engine block is slightly damaged, repair is sufficient. However, if the damage is severe, the car engine needs to be replaced. Below is detailed information about car engines: 1. Overview: The car engine is the device that provides power to the vehicle, determining its performance, fuel efficiency, stability, and environmental friendliness. Depending on the power source, car engines can be classified into diesel engines, gasoline engines, electric vehicle motors, and hybrids, among others. 2. Others: Common gasoline and diesel engines are both types of reciprocating piston internal combustion engines, capable of converting the chemical energy of fuel into the mechanical energy of piston motion and outputting power. Gasoline engines have high rotational speeds, are lightweight, produce less noise, are easy to start, and have lower manufacturing costs. Diesel engines have higher compression ratios and thermal efficiency, offering better fuel economy and emission performance compared to gasoline engines.
Last time my engine suffered cylinder scoring and it was a real headache. If the cylinder block is slightly damaged, it can actually be repaired. You can use laser cladding or cold welding technology to patch the cracks, then use CNC boring to restore the inner wall to a smooth finish, which might cost around three to five thousand. But if the entire cylinder block is deformed or cracked through, you must replace it! Repairing is not only time-consuming and labor-intensive, but the strength also won’t match the factory standard. My neighbor’s old Bora was forcibly patched, and after half a year, coolant started leaking from the cracks, eventually bending the piston connecting rod. Especially now with many all-aluminum engines, welding is even more difficult—it’s better to just replace the cylinder block assembly for peace of mind.
