Will the Engine Get Waterlogged When Driving in the Rain?

[OTalia]

Parking a car outdoors during heavy rain generally won't cause water ingress, but if flooding occurs and the water level rises above half of the tires, the engine may get waterlogged. Here are methods to check for engine water ingress: 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 has entered 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 ingress, and check the intake pipe and manifold for clear traces of water exposure. 3. Check the spark plugs: Remove the spark plugs from each cylinder and check if they are damp. Moisture indicates signs of water ingress in the engine. 4. Inspect the engine cylinder walls for carbon deposits: During normal engine operation, each piston reaches the same top dead center position, making the top dead center marks on the cylinder walls clearly visible.
