A two piece valve cover with a removable top cover is constructed of thin gauge material for use on an internal combustion engine having an engine cylinder head and a plurality of valve rocker arms. The cover includes an elongated dome like upper portion which acts as a cover over the rocker arm and cylinder head area of the engine whose external continuous surface does not conform dimensionally with those of a peripheral base flange. A separate peripheral flange portion includes a sealing groove adapted for sealing engagement to the cylinder head through the use of a sealing gasket member. A plurality of apertures through the cover portion can be inserted to secure the cover to rigid flange portion. The outer rim of the top cover is forced into the O-ring groove by the downward action of the cover being attached to the base flange and an outward action of a tapered wedge design of a primary groove, thus forming a seal and the structural rigidity of a one piece product.
