Abstract: A cover for use on the forward, timing chain, end of a number of different model multi-cylinder, automotive vehicle type internal combustion engines is formed of an integral cast metal dish-like shape having a forward wall and a surrounding edge wall which define a cavity. The edge wall is shaped to engage and mount upon the forward end of an engine to cover the timing chain and the engine crankshaft extends through a seal mounted within a hole in the wall, with the seal being located upon the exterior of the cover wall for removal without removing the cover. A fuel pump mounting opening, which may be blocked by a removable plate, is formed in the cover edge wall so that a fuel pump may be optionally mounted within the cover by removing the plate. A distributor mechanism receiving opening is formed in the upper end portion of the cover edge wall and alternative screw receiving holes formed in the cover permit mounting different, preselected distributor mechanisms therein.
