Hydro-locking is a result of water being sucked through the air intake, not the incredibly small amounts of atomized fuel shot into the cylinders by the fuel injectors.

How does water being sucked into the air intake hydrolock an engine without also bending a connecting rod or otherwise causing the engine to stop? That is the definition of hydrolock. Too much liquid in the cylinder, regardless of how it got there (air intake being the obvious/common way).

Were talking about injectors spraying contaminated gasoline, not submerged intakes.

Water in the combustion chamber leads to hydro lock. By injector does take a lot longer, but water in cylinder is hydro lock.

In a running engine water is sometimes injected into the cyclinders to cool down the temps and prevent pre-detonation, especially in older turbocharged engines with high boost. Menthol was also used.

You seem to have some things confused.

A controlled amount injected into cylinders with the engine tuned properly for it is how water and menthol injection systems work. An engine that can barely run because it’s choking on diluted with water gas is not the same thing at all. Some of that water is still collecting in the cylinder, enough and you can easily get a bent connecting rod. It doesn’t take much.
