Will the car engine really be worse than the original after an overhaul? This problem has been plaguing many car owners.
Engine overhaul usually refers to lifting, disassembling, inspecting, cleaning, repairing or replacing problematic parts, and repairing the engine in accordance with the manufacturing specifications, parameters and standards of the original manufacturer at that time. Although engine overhaul is a labor-intensive job, it is often less costly than replacing an entire vehicle or replacing it with a new one. However, there may be some problems when servicing.
First of all, the maintenance personnel may not tighten all the screws according to the manufacturer's requirements, which will lead to uneven tightening torque of the screws, which will have a greater impact on the performance of the engine. Secondly, even with ** parts, there are still tolerance fit issues between mechanical parts, which can lead to a decrease in engine performance. In addition, most engine repairers rely on their own experience to assemble, and it is difficult to guarantee that the repaired engine will be restored to the original level.
While an engine overhaul is a complex job, if you have to do it, choose a reliable repair shop and learn as much as you can about it.
