Abstract

A cylinder liner (2) for a cylinder block has a contouring (6) at one end. The contouring (6) serves to support the liner (2) on a sleeve (4) inside a die-casting tool. When the liner (2) is cast in, recesses (10) of the liner (2) are filled by the material of the cylinder crankcase whereby preventing the liner (2) from seating toward an oil chamber (14). The invention also relates to a method for producing a cylinder liner of the aforementioned type.
