im not saying the oil temping issue is not causing crank breakage, but it still isnt a solid thing for me. i work on alot of abused stuff, and for the most part, as long as there is oil in the engine with decent pressure, it's pretty much going to be ok. ive drained pure transmission oil out of engines, and engine oil out of transmissions. a broken crankshaft just doesnt happen very often in anything but the duramax engines, from what i can tell.
also, an engine that has lost its oil pressure would tend to trash the bearings from metal to metal contact. (there is no film being maintained between the parts)
my bearings all looked fine and yet the crank broke. so, in my mind, the oil pressure didnt drop off in my engine. yours, having spun bearings, could have very possibly had a pressure issue, since the loss of oil film meant your crank journals grabbed the bearings and tried to become one with them.
i just don't know. it is frustrating to not know a solid cause of this. not discounting anything at this point, just trying to reason my way through to a solution.

Was driving around 60 mph n had just started getting into the throttle when it popped n rattled n died. The balancer wobbles n you can wiggle it when you pry it. The engine runs smooth...maybe just a little vibration.... What is the chance my block is ok n didn't mess to much up?
