Does Water in the Engine Require Engine Disassembly?

[DelIvan]

Whether water in the engine requires disassembly depends on the extent of the damage. From a repair perspective, an engine teardown inspection is necessary. Reasons for engine disassembly: Since the extent of engine damage varies, if water enters the engine block, it can typically cause connecting rod deformation. In severe cases, it may damage the engine block, requiring replacement of the cylinder block. Additionally, if the cylinder head valves are also deformed, it is recommended from a repair standpoint to replace the short block, i.e., the complete engine assembly. Cases where engine disassembly is not required: If the vehicle stalls in water and is not restarted, the engine, even if water enters, will not suffer severe damage. After draining the water, the engine will operate normally without any impact, but the engine oil must be replaced.
