I have had the divider inner plate have a crack and would spray water into the chest. It would leak more after it ran for a few minutes as the crack would open up due to the heat. This usually only effects 1 side of engine. Could be a blown/rotted divider gasket as well. Usually pretty obvious as the chest will be very clean on the one side. Just my experiences.

Just my experiences. at one time it did loose power pass after pass (crack opening) i m gonna do head gaskets and exhaust plate sandwich/ divider clamshell cover makes it easy maybe @6000 water psi is 20 and engine cant swallow it , thanks james.
