What is the solution for water entering the engine cylinder?
3 Answers
The solutions for water entering the engine cylinder are as follows: 1. Cleaning: Simply clean the components. If the engine only has water vapor mixed in from the air filter, clean the water vapor from the air filter, throttle valve, and cylinder. 2. Oil change: If water enters the engine cylinder but does not affect normal driving, and there is a loud noise, it may indicate a small amount of water in the oil or gasoline. In this case, change the oil and clean the related engine components. 3. Engine replacement: If a significant amount of water enters the engine cylinder, causing severe damage to engine components, a new engine replacement is required.
The other day my car drove through a deep puddle during heavy rain, and the engine suddenly started shaking and stalled. Turned out water had entered the cylinders. I immediately turned off the engine and avoided tampering with it, since water can't be compressed—forcing a start could damage the pistons. I opened the hood, removed the spark plugs, and used a manual pump to slowly extract the accumulated water. Then I checked the engine oil; if it showed a milky, watered-down appearance, I’d replace both the oil and filter right away. After draining the water, I tried starting it again—if issues persisted, internal damage was likely, and a repair shop visit would be necessary. They’d need to disassemble the engine for a thorough cylinder cleaning, seal replacement, etc. Water ingress poses serious risks: minor cases cost hundreds in repairs, while severe ones can total the engine. So I recommend avoiding standing water while driving—don’t proceed if it’s above the axle height—and maintaining the cooling system regularly to prevent leaks. It’s safer and saves money long-term.
Engine water ingress is a serious issue that requires immediate action to prevent further damage. Upon discovery, I promptly turned off the engine, engaged the handbrake, activated the hazard lights, and pulled over. Never attempt to restart the engine, as this increases internal pressure and risks cylinder block damage. Check if the air filter is soaked—if wet, remove it to dry or replace it with a new one. Removing spark plugs to drain water is a preliminary measure, but it's best to call a tow truck for professional repair. The shop will use specialized equipment to clean the cylinders, inspect for rust or bent connecting rods, and replace contaminated oil. The entire process may cost over a thousand yuan, depending on the extent of damage. For prevention, heed water depth warnings while driving, avoid risks in rainy conditions by slowing down, and regularly inspect engine seals to maintain dryness. This ensures safety and saves money.
