The silt particles present in flood water could accumulate deep inside of the engine and hang on to the rough casting surfaces of all the internal workings. These particles are so small that when they are in solution they will infiltrate the oil clearance of a bearing. When the water dries, they will form a layer of dust within the bearing. The dust will wick up the oil from the surface and water vapor from the air will start to rust the steel surface over time. The dust may also have acids and alkalies (caustics) attached to it, and together with water vapor will etch the bearing and journal surfaces. | The silt particles present in flood water could accumulate deep inside of the engine and hang on to the rough casting surfaces of all the internal workings.

Many flooded engines will just have to wait, sometimes after the winter freeze-up, sometimes even longer. Internal damage and cracked blocks and heads are often the result of frozen water. Sometimes they will end up being junked for the cast iron.

Many flooded engines will just have to wait, sometimes until after the winter freeze-up, sometimes even longer. Internal damage and cracked blocks and heads are often the result of frozen water. Sometimes they will end up being junked for the cast iron. If these engines are gotten to ''before'' such damage occurs, it may be possible to salvage them intact. |
