Will Disassembling the Engine Affect Its Performance?

[Meghan]

Disassembling the engine will not affect its performance, as long as the disassembly and reassembly are carried out according to the standard procedures, which do not harm the machine's functionality. Typically, engine disassembly for repair is only necessary in cases such as water ingress into the engine, mixing of oil and water in the engine, or damage to the engine casing leading to oil or water leakage. Engine power loss and oil burning: If there is oil leakage, it is likely caused by aging valve stem seals or the alignment of piston ring gaps. For these two scenarios, priority should be given to inspecting these two automotive component groups before deciding whether an engine overhaul is required. When the engine produces abnormal noises: If severe piston slap is detected or if the engine's bearing shells (big and small ends) are severely eroded along with significant crankshaft wear, an overhaul should be considered. Cylinder wear reaching overhaul standards: Regardless of the symptoms the car exhibits, the ultimate criterion for deciding on an overhaul is the cylinder wear. If the cylinder's out-of-roundness reaches 0.125mm per 100mm of bore diameter, or if the cylinder's taper wear reaches 0.4mm per 100mm of bore diameter, meeting either of these conditions warrants consideration for an overhaul.
