Should a car engine damaged in an accident be scrapped or repaired?

[ParkerRose]

When a vehicle is damaged in a traffic accident, the general approach is to repair it. However, if the repair cost approaches or exceeds the vehicle's value, it may be considered for scrapping. In special circumstances, or if one party has specific requirements, both parties can negotiate to decide whether to repair or scrap the vehicle. For example, if the engine block is deformed or cracked due to freezing in an accident, or if piston failure causes severe damage to the block making it irreparable, such engines are not suitable for repair. For some common engine issues like excessive carbon buildup, severe "engine knocking," "cylinder scoring" due to lack of lubrication, bearing corrosion leading to engine shutdown, valve burning, or tappet spring breakage causing intake/exhaust obstruction resulting in insufficient power or starting difficulties, professional repair shops can be chosen for thorough inspection and maintenance based on the situation.
