What are the mild symptoms of water entering the engine?

[LaGeorge]

The mild symptoms of water entering the engine are insufficient vehicle power and idle speed vibration. Methods to determine whether water has entered the engine: 1. Check the air filter and the lower housing of the air filter for obvious signs of water ingress, and inspect the intake pipe and intake manifold for clear traces of water passing through; 2. Examine the condition of the engine oil. Normal engine oil colors include light yellow, brown, and transparent colorless. Pull out the dipstick, wipe it clean, and then reinsert it. If a milky white mixture of oil and water appears, it indicates water has entered the engine; 3. When there is water in the engine fuel or combustion chamber, the water is heated by the combustion heat in the cylinder and turns into steam, which is discharged from the exhaust pipe forming white smoke. The appearance of white smoke indicates water has entered the engine.
