Can a diesel engine hydrolock?

Diesel engines are more susceptible to hydrolock than gasoline engines. Due to their higher compression ratios, diesel engines have a much smaller final combustion chamber volume, requiring much less liquid to hydrolock. The result is that a diesel engine is more likely to suffer catastrophic damage.

How do you fix a Hydrolocked engine?
