Abstract
A casing cover (1, 10, 20) for an internal-combustion engine, particularly valve covers or oil pans, for being mounted detachably and fluid-tight to the engine block (5, 13, 21), having a peripheral edge that is profiled to receive an elastomer seal (3, 12) at the edge (2, 11) of the casing cover (1, 10, 20). The cover is provided with an axial extension (7, 14) that is oriented in the direction of the engine block (5, 13, 21) and is disposed at an inner portion of the edge (2, 11) of the casing cover (1, 10, 20). The extension is positioned to project axially beyond the sealing surface (4, 15), an engine block wherein the casing cover is inserted so the casing cover is at least positioned correctly on the engine block.
