How Long Can a Repaired Water-Damaged Engine Last?

[KevinLynn]

Generally, a repaired water-damaged engine can last for 4-5 years without issues. Detailed explanations are as follows: 1. When the damage is minor: The lifespan of the repaired engine depends on the extent of damage. If the engine only suffered water ingress without actual damage, it simply requires removing the spark plugs to drain the water and replacing the engine oil and coolant. In this case, the engine itself remains unaffected and can last as long as a normal car. 2. When the damage is severe: If water enters the cylinders along with the engine, the situation becomes complicated. Water in the cylinders can cause connecting rods to bend or even break, potentially damaging the engine block. In such cases, it's hard to predict the outcome as the engine needs to be disassembled to replace the connecting rods or even the entire block. The durability of the repaired engine is uncertain and depends on the quality of repairs and replacement parts. If the engine is carefully repaired after water damage, it can still function normally. However, if the parts are of poor quality or the repair work is subpar, the engine may develop problems during future use.
