Water Injection

[Bruce]

Guess we better all go to air cooled engines, heck a blown headgasket can
fill a cylinder with water.
Better dump that port type injection, a leaking injector can dump a bunch of
fuel in a cylinder.
Yes, you can fill a cylinder with water, but like you point out thinking
things out can avoid those pit falls.   A check valve or two can help.
Like so many things, a failure of a part can cause problems.
