What problems are prone to occur after an engine overhaul due to water ingress?

[MorganDella]

After an engine overhaul due to water ingress, the car may experience shaking, reduced power, and frequent malfunctions. Measures to inspect a water-damaged car engine: 1. Measurement methods: By using measurement techniques, the condition of each cylinder's connecting rod can be determined one by one. If all cylinders are found to be in good condition, the engine can be reassembled after replacing the fluids. 2. Cylinder connecting rods: If problems are detected in some of the cylinder connecting rods, mechanics often recommend replacing all connecting rods and pistons for better repair results, which is reasonable. Not all engines that have been submerged or stalled due to water ingress require replacing the connecting rods and pistons; the decision should be based on actual measurement results. It is advisable to personally observe during the repair process.

After a major overhaul due to engine water ingress last time, I drove for a while and found that the car always made a clicking noise when starting. It felt sluggish and lacked power, possibly due to severe cylinder corrosion or rusted crankshaft bearings. Incomplete water drainage can easily cause secondary issues. Later, problems like oil emulsification and white smoke emerged, and it was found that the piston rings were stuck. This led to frequent oil changes and a significant increase in fuel consumption. The mechanic mentioned that after a major overhaul, it's essential to regularly check if the oil color is cloudy. It's best to avoid high-speed driving during the break-in period to prevent connecting rod deformation, which could lead to complete engine failure. The total repair costs were quite substantial, so I advise everyone not to skimp on maintenance after water ingress to save money.

My family has an old car that had its engine repaired after water damage, and it often has minor issues. Not only does it have difficulty starting, but it also stalls frequently, affecting daily commutes. The root cause is that not all the water was completely removed, leading to severe rust on the crankshaft and bearings. During the major repair, it seemed fixed, but the aging seals and residual impurities in the oil system can easily cause parts to stick or break. Subsequent inspections revealed slight deformation in the connecting rod, causing dragging issues during startup, making repairs time-consuming and costly. I regularly check the oil level and color changes—if it appears milky white, immediate action is needed. Cars repaired after water damage require extra attention to ensure safe driving on the road.

I once bought a used car whose engine had been overhauled due to water damage. After driving it for a few months, I noticed a significant drop in power, strong jerking during acceleration, and much higher fuel consumption than normal. Upon inspection, I found that rust and corrosion inside the cylinders had caused piston ring sticking or crankshaft wear. Later, issues like delayed starting and abnormal noises also emerged. These problems all stemmed from residual water not being thoroughly cleaned out, and post-overhaul, damaged parts were more prone to recurring failures. My advice is to change the oil frequently after water damage repairs and check the engine temperature before each drive to avoid breaking down midway. Spending on maintenance can save you from bigger troubles.

After my engine was overhauled due to water ingress, I've been constantly worried about safety while driving, especially after experiencing sudden power loss on the highway, which nearly caused an accident. The reason is that incomplete overhaul leaves residual water, easily causing electrical short circuits or sensor failures, leading to unexplained engine stalling. Additionally, bent connecting rods or rusted bearings may result in a high risk of internal component fractures. Subsequent checks revealed severe oil contamination, and the replaced parts also had a short lifespan, requiring higher maintenance costs. I recommend conducting more short-distance tests after repairs, monitoring changes in engine sounds, and ensuring no abnormal noises before driving normally—safety first.

I've seen a friend's car that had its engine repaired after water ingress, and within a few months, problems arose, such as difficulty starting and a sharp increase in fuel consumption. The main issue was that the water wasn't completely drained, leading to corrosion of internal parts, with common problems like rusted and stuck crankshaft bearings and damaged piston rings. After a major overhaul, it's also prone to oil contamination or seal failure, causing leaks or abnormal noises. Subsequent recommendations include regularly checking the engine oil condition—if it's emulsified or discolored, change the oil immediately. During the break-in period, gently press the accelerator to reduce load, which can extend the engine's lifespan. Repairing water ingress is costly, but being careful can help avoid pitfalls.
