What problems will occur if water enters the engine?

[AnthonyLynn]

The following problems may occur if water enters the engine: 1. Engine stalling: After water enters the engine, the spark plugs fail to ignite, causing the car to stall while driving. 2. Failure to restart after stalling: Water entering the distributor cap causes the distributor to lose its normal ignition function, making it impossible to restart the engine. 3. Engine damage or hydro-lock: When water enters the engine, its incompressibility may cause the connecting rods to bend or break, leading to cylinder wall damage. Additional information: Signs of water entering the engine include checking for carbon deposits on the spark plugs and cylinder walls. When water enters the engine, its incompressibility prevents the piston from reaching the original top dead center position, resulting in a shorter piston stroke and a noticeable downward shift in the top dead center position.
