G-Man and Larry;
Don't think the noise was a bearing. That engine's bottom end is like the rock of gibraltar. If a bearing spins the sound is knock like as the engine keeps running. Larry describes a loud band which to me, sounds more like a charged cylinder blowing part or all of it's power stroke past a blown head gasket. I have heard that sound many many times on racing engines. Sounds like an old steam engine if the motor runs at all. I didn't read any of what larry wrote to indicate no or low oil pressure, so I think it's all top end.
