Will Water Entering the Car's Air Intake Affect the Engine?

[AnastasiaLee]

Water entering the engine's air intake can affect the engine. Detailed explanation is as follows: 1. When the damage is minor: The lifespan of the engine after repair depends on the extent of the damage. If the engine only has water ingress without any damage, simply removing the spark plugs to drain the water and replacing the engine oil and coolant will suffice. This has no impact on the engine itself, and its lifespan remains the same as a normal car. 2. When the damage is severe: If water enters the engine along with the cylinders, the situation becomes complicated. Water in the cylinders can cause the connecting rods to bend or even break, potentially damaging the engine block. In such cases, it's difficult to assess the damage without disassembling the engine to replace the connecting rods or even the engine block. After such repairs, it's uncertain whether the engine will function properly, as this depends on the quality of the repair and the parts used. If the engine is damaged due to water ingress and requires disassembly, careful repair can restore normal operation. However, if the parts are of poor quality or the repair technician lacks the necessary skills, the engine may develop problems during future use.
