http://en.wikipedia.org/wiki/Hydrolock

In automotive terminology, a hydrolock is the immobilization of an engine's pistons by a liquid (usually water, hence the prefix "hydro-"). Hydrolocking occurs when liquid fills a cylinder on the intake stroke and, due to the incompressibility of a liquid, makes the compression stroke impossible. This, in turn, prevents the entire engine from turning, and can cause significant engine damage if one attempts to forcibly turn over or start the engine.

ususally it happens when ppl have a cold air intake, on high throttle and going over deep water. sucks it up like a straw.

I think its best to say it can anytime driving though deep water.

Can also happen if your head gasket is blown, but visably cannot be seen, ie gasket blown between water channel and cylinder.

Stop after a drive, pressurised water system bleeds into cylinder through blown gasket, driver starts up next time, cylinder fires other cylinder full of water and bang!

yeah, hydrolock is if you have a CAI (cold air intake) and if the pod is completely submerged in water from a deep puddle, to prevent this you can get a bypass vavle..
