This is the #6 rod and piston. It got so hot the rod bearing welded itself the the crank journal! I had to cut the left side of the mangled rod cap to get it out of the block. The right side was already snapped off.




#6 is the worst. I have not yet determined the cause of the oil pressure drop that caused all this damage. This is how it looked when I opened it up.

#5 got very hot as well but didn't weld itself.

The rest of them looked OK! There was trash run through the bearings but no excessive heat or scoring.
