Patent ID: 8176967

Claim:
A method for producing a cast component of an internal combustion engine with a pipe cast into the cast component in a casting process with: expendable molds and a permanent pattern, or with permanent molds, the method comprising steps of: integrating a separate pipe holder in a split outer mold or a solid core mold; inserting the pipe in a retaining section of the separate pipe holder in such a manner that the retaining section surrounds at least part of an outer circumference of the pipe with little play; mounting the solid core mold in the split outer mold; and introducing casting material in liquid form to form the cast component cast in such a manner that during the casting, due to the little play of the pipe in the retaining section of the separate pipe holder, the pipe can expand in an axial direction but is secured against radial displacement caused by buoyancy forces of the casting material.
