What Causes Water in the Engine Cylinder?

[DiFelix]

Reasons for water entering the engine cylinder: Water entering through the air filter: If the engine only has a mixture of water vapor entering through the air filter, the issue is minor and can be resolved with simple treatment. Small amounts of water in the oil or fuel: There may be small amounts of water in the oil or fuel, requiring an oil change and cleaning of related engine components. Minimal water in the engine: If there is more water but not a significant mixture, and the car hasn't been started, the engine won't be damaged. In this case, the water needs to be drained, the interior cleaned thoroughly, reassembled, and the oil replaced. Significant water in the engine: If there is a significant amount of water in the engine and it cannot run after starting, the only options are to replace the engine or scrap the car entirely.
