Here is the damage... Crank is snapped in half, right behind the #3 bearing journal. In front of #7 rod. I had a brand new timing set and harmonic balancer and a good used flywheel for a 6.2L on the motor... wondering if these motors are known for snapping cranks even with everything else in good shape? Or should I be looking for other problems somewhere? I'm gonna have to tear it down now to remove the crank anyway so I'm thinking a cheap rebuild, new gaskets and bearings is in order just because its torn down. Don't think I need to redo the rings as it didn't use oil and had good compression already. Started without hesitation, even in cold weather (manual glowplug setup as well).
