Abstract

A rocker cover assembly for a cylinder head of an internal combustion engine includes a rock cover, a gasket element and a stabilizing core. The gasket element is disposed between the rocker cover and the cylinder head, and includes a sealing material. The stabilizing core is inserted in the gasket element and surrounded at least essentially completely by the sealing material of the gasket element. The stabilizing core is isolated from the rocker cover such that the sealing material of the gasket element is arranged between the stabilizing core and the rocker cover.
