Personally I am not of the opinion that the fault lies in the rods. I believe its in the weakened block and the resutling failure between the head and block seal.

The arguement about carbon building up on the piston also rings true to me.

Either scenario does not point to a weak rod but a condition inside the combustion chamber that the rod was not designed for....either carbon build up or some kind of liquid, either oil or coolant.

I am pretty sure we have heard from a couple of folks at least who had bent rods after the "updated" rods were installed.
