Abstract
A casing cover (1, 10, 22) for an internal-combustion engine, particularly valve covers or oil pans, to be mounted detachably and fluid-tight to an engine block (5, 13, 23), having an elastomer seal profile (3, 12, 28) disposed at the peripheral edge (2, 11) of the casing cover (1, 10, 22), and an inside (6, 17), axial extension (7, 14, 26) oriented in the direction of the engine block (5, 13, 23) disposed at the edge (2, 11) of the casing cover (1, 10, 22). The extension projects axially beyond the sealing surface (4, 15) of the engine block when the cover is installed, and a seal (20, 29) is disposed at least between the axial extension (7, 14, 26) and the engine block (5, 13, 23).
