Cylinder block is made of one piece of spheroidal cast iron. It broke due to the impact of a failed piston rod. It is evident observing the picture, there are no possibilities to repair the damaged cylinder block. Spheroidal cast iron can not be repaired by welding as the material can not be welded in a easy way. Mechanical repear with metal locking was not feasible due high geometrical complexity and to high deformation of the engine block. For this component a complete subtitution was necessary.
