Can the Engine Start If It Gets Water Inside?

[Marley]

Do not attempt to restart the car if the engine has taken in water. Water entering the engine is absolutely fatal internal damage to a vehicle's engine. Once water enters the engine, at best, the spark plugs may fail to ignite, causing the engine to stall directly; at worst, it could lead to cylinder explosion. Principles after wading through water: When a vehicle wades through water, water enters the cylinders through the intake manifold. Due to the incompressibility of water, the piston's stroke will shorten, leading to bending or breaking of the engine connecting rods. Under extreme conditions, the broken connecting rods may fly out and penetrate the engine block. Reasons for the car stalling in water: After the distributor cap gets wet, it loses its normal ignition function. The engine's air filter element takes in water, increasing intake resistance and allowing water to enter the combustion chamber, making the spark plugs unable to ignite. Restarting the engine under these conditions can easily cause cylinder explosion.
