A casting manufactured from aluminum or an aluminum alloy, provided with at least one core hole, the core hole being closed by a plug secured therein, the plug being manufactured from aluminum or an aluminum alloy and being sealingly secured in the core hole at least substantially through deformation of a portion of the plug and/or the casting. <IMAGE>
