Abstract
An intake manifold assembly and a valve cover is pivotally supported by the intake manifold assembly for rotational movement relative thereto. Preferably, a hinge assembly pivotally supports and connects the valve cover to the intake manifold assembly. During assembly of the engine, the intake manifold assembly is secured to a portion of a base engine assembly such as the cylinder head. Specifically, threaded fasteners may secure a flange of the intake manifold assembly which is adjacent to the hinge assembly to the cylinder head. The valve cover is rotated relative to the intake manifold assembly and into engagement with the cylinder head so that a valve cover gasket sealingly engages the cylinder head. Fasteners on a side of the valve cover opposite the hinge assembly secure the valve cover to the cylinder head. Fasteners are not needed on the side of the valve cover that is adjacent to the hinge assembly since the fasteners along the intake manifold assembly flange retain the side of the valve cover assembly adjacent to the hinge assembly into engagement with the cylinder head.
