Think about it like this engines work on the suck squeeze bang blow principle. Which means air is taken in and compressed then spark is added and it is sent out as exhaust. Since water is not compressable when the piston is trying to squeeze it is unable to do so, which inturn means something has to give. The weak link will always give whether that be rods, lifters, even the cylinder wall so the damage can run the full spectrum of parts that can break. Once one of these parts breaks it usually takes other pieces along with it. Also once water is taken in corrosion will start to form and that means cleaning every part it touched.
