Abstract

1. An insert (1, 1'; 10, 10') for expansion joints in the bottom part, on the combustion chamber side, of a cast light-metal cylinder head for internal combustion engines, especially Diesel engines, the insert being formed to provide a securing position in the casting mould, characterised in that one or more retaining part(s) (arch piece 2; ring parts 11, 11') are connected to the insert (1, 1'; 10, 10'), and the insert and/or a retaining part have a configuration which is adapted to a casting core of the casting mould for retention engagement by virtue of the application of force or of shape.
