What to Do If Water Enters a Diesel Engine
1 Answers
Diesel engine water ingress solutions: 1. If water enters the cylinder, do not attempt to start the engine as air can be compressed. 2. Since water cannot be compressed, starting the engine may cause cylinder head deformation or connecting rod/crankshaft fracture, resulting in engine failure. To drain water, remove each cylinder's fuel injector and crank the starter motor to expel water from cylinders. 3. Replace the air filter. Water contamination in engine oil is less critical as oil is denser than water - the oil pump pickup tube sits at the lowest point of the oil pan. Engine heat will evaporate any water in the oil. 4. Replace diesel fuel if contaminated, as water in fuel causes white exhaust smoke and poor acceleration. These measures will allow temporary operation.
