Each camshaft cover is secured to the cylinder head with a mixture of bolts, studs and nuts. Rubber washers seal the holes in the covers and sleeves control the compression of the rubber washers.
Threaded inserts are installed to each cover to allow for the attachment of the ignition coils.
Each camshaft cover is equipped with a breather. The left side cover has a baffle plate which collects engine 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 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 camshaft cover gasket. There are 3 separate gaskets, located in the center of the camshaft cover that prevent engine oil leaking into the area around the fuel injectors, spark plugs and ignition coils.
