General bad stuff happens.
A hydrolock can occur if some idiot tries to, say, drive his little car through a deep puddle, and the engine snorks up liquid water through the air intake. Less frequently, a blown gasket can allow coolant to seep into a stopped engine, and if it fills the cylinder full enough before someone comes along to try and start it again, *wham* instant hydrolock as soon as they try to start it next time.
