Yeah I dont even have a clue there really wasnt a telltale head gasket failure. The engine ran fine, weird sht just starting to happen. One day when I went to start it it acted like the batt was stone dead and it wouldn't crank. After several attempts, it turned over, and started. ( I'm now convinced that there was water in that cylinder and the engine was hydrolocked.)I'm curious to see how deep those cracks go.... You thinking the cracks compromised the HG seal and caused your issues (I would expect the seal to be between the liner and head gasket)? Have you straight edged the block and heads yet to see what the distortion is? I'd check to see if the liners have moved/protruded/dropped which caused your diagnoses HG issues.
Excuse any ignorance I have on this motor, I don't know this platform very well.
But after it started, it ran fine, and there was no telltale smoke or smell coming out of the tail pipe.
Wherever, or however the water got in neither the deck, or the head show that.
It doesn't matter anyway..there is only a very small group of people that this thing appeals to anyway, and most of them are too far removed from wanting to take on such a finicky bitch like this engine.
