A rocker cover assembly comprises a rock cover; a gasket mechanism between the rocker cover and the cylinder head; and stabilizing core. The gasket mechanism includes a sealing material. The stabilizing core is inserted in the gasket mechanism. The stabilizing core is surrounded completely by the sealing material of the gasket mechanism and is isolated from the rocker cover, such that the sealing material of the gasket mechanism is arranged between the stabilizing core and the rocker cover. An independent claim is also included for manufacturing a rocker cover assembly comprising manufacturing a rocker cover and a stabilizing core of the rocker cover assembly by a plastic injection molding process, the stabilizing core is situated on an outside edge of the rocker cover and connected to the rocker cover by a guide web as a breaking point; detaching the stabilizing core at the breaking point from the rocker cover; and sheathing the stabilizing core with an elastomer while simultaneously securing the stabilizing core to the rocker cover.
