The thing sounded horrible so close to throwing the rod the bearing cap bolts stretched and the bearing came loose and was hammered flat. and was just spinning in the journal causing even more problems. starving the rod of oil just compounding the issues. A while back we had a Cat engine that drove in with a broken crank.
DFBrews just said that the wrist pin went bad and driving it more compounded the issues.

DfBrews... whats the story on that piston crown. I have never seen a design like that. I am referring to the cone and what looks like a strange internal pocket around that. Is that to create some type of swirl to better the burn?
