Each camshaft cover is secured to the cylinder head with 15 bolts and 1 stud and nut. A grommet seals the holes in the cover and a sleeve controls the compression of the grommet.
Threaded inserts are equipped to each cover to allow for the attachment of the ignition coils. A plastic cover is equipped over the ignition coils and is secured with snaplock studs.
Each camshaft cover is equipped with a breather. The left side cover has a baffle plate which collects oil vapor and allows it drain back into the oil pan via the cylinder block. The left side breather provides for engine full load operation and vents cylinder block emissions into the left side air filter outlet. The right side cover is equipped with an omega plate and a pressure control valve. The right side breather provides for engine part load operation and vents cylinder block emissions into the throttle which is integral with the supercharger.
A groove in the outer edge of each cover provides the location for the re-useable camshaft cover gasket. Three separate gaskets, located in the center of the camshaft cover, prevent oil leaking into the area around the fuel injectors, spark plugs and coils.
