Ol Morgan has a great idea....cam lobe. Piece of debris could have gotten into the lifter and scored the lobe on the cam. When this happens, it is usually present at operating temp as the oil has thinned out. It's closer to the top end just like we thought and sounds pretty damn close to this 6.4. This is one of the things that could really makes sense so far...especially since its oil temp dependent. I guess it could still be a bearing too but either way...it's bad news LOL
