Engine cover having a retainer to secure an engine accessory

Abstract

A cam cover for a cylinder head of an internal combustion engine has an aperture in the cam cover adapted to permit spark plug installation into the cylinder head and two tabs protruding vertically from the cam cover adapted to retain a boss extending from an ignition coil. The ignition coil has a portion adapted to fit over the spark plug and an orifice through the boss. The cam cover also has a recess between the tabs with the recess extending into the cam cover which is adapted to accept a self-tapping screw in the event of a tab failure. The tabs have a varying cross-section along their length such that they allow the orifice to slide over the tabs squeezing the tabs together and then snapping into place when the orifice clears the ramps on the side of the tabs.
