Will the Engine Take in Water on Rainy Days?

[StLondon]

When a car is parked outdoors during heavy rain, water generally won't enter the engine. However, if the water level rises above half of the tire height, the engine may take in water. How to check for water in the engine: 1. Check the engine oil: The simplest method is to inspect the oil color for abnormalities. If the oil turns milky white, it indicates water presence in the fuel tank or engine. 2. Inspect all pipelines for water ingress: Examine the air filter and its lower housing for obvious signs of water, and check the intake pipe and manifold for clear traces of water passage. 3. Check the spark plugs: Remove the spark plugs from each cylinder and check if they are damp. Moisture suggests signs of water in the engine. 4. Inspect the engine cylinder walls for carbon deposits: During normal operation, each piston reaches the same top dead center position, making the top dead center marks on the cylinder walls clearly visible.
