Really? Please explain to me how and why the oil cooler leaking couldn't hydrolock the engine.
Second, If the liquid causing the hydrolock was expelled via the GP holes "violently", wouldn't, or couldn't that lead to bent rods and such? Just curious. Please school me, Tim

becuase for an engine to hydrolock water/oil has to get between the pistons and th ehead, or into the intake manifold ,then drawn in threw the valves.
a bad oil cooler can leak coolant into the oil, but there is no way for it to get ontop of the piston via the intake or head, since all it does is sit around unpressurized in the pan..........
they usually hydrolock when sht down hot and there is pressure in th ecooling system. the coolant then leaks out of the crack or gasket till it fills up the bad cylinder partially, then when you go to crank it, it performs the bangstop theory where liquids can't compress
okay, on violently. you crank it by hand 2 revs, because this runs each cyl through its compression stroke, thus expelling MOST of the coolant up through the glow plug hole slowly. then you crank it with the start the remaining particals expell through the glow plug holes. no glow plug,= no compression. thus allowing a path for water to escape. it will expell violently, put not enough to hurt it if you keep just bumping the starter. y ou ever done a compression test on a diesel? the air comes out violently out of the empty holes, its just some liquid added to the mix when you do it this way..
i have unhydrololcoked MANY 6.5L's and i do know what i am doing.
lots of junk
