Each camshaft cover is secured to the cylinder head with bolts, studs and nuts. The grommet seals the holes in the camshaft cover and the sleeve controls the compression of the grommet.
Threaded inserts are fitted to each cover to allow for the attachment of the ignition coils. A plastic cover is fitted over the ignition coils and is secured with snaplock studs.
A groove in the outer edge of each cover provides the location for the re-useable camshaft cover gasket. Four separate gaskets, located in the center of the camshaft cover, prevent oil leaking into the area around the fuel injectors, spark plugs and ignition coils.
The Bank 1 camshaft cover is fitted with an oil separator and 2 positive crankcase ventilation valves. The breather within the camshaft cover provides for engine part load operation and vents cylinder block emissions into the supercharger inlet port.
The Bank 2 camshaft cover has a baffle plate which collects oil vapor and allows it to drain back into the oil pan through the cylinder block. The breather within the camshaft cover provides for engine full load operation and vents cylinder block emissions into the left side air filter outlet.
