The camshaft covers are manufactured from vinyl
ester composite. The A bank camshaft cover
incorporates an outlet for the full load engine
breather. The B bank camshaft cover incorporates
the engine oil filler cap and an outlet for the part
load engine breather. Identical oil separators are
incorporated below the breather outlet in each
cover (see Crankcase Ventilation, page 35).
Silicon rubber in-groove gaskets seal the joints
between the camshaft covers and the cylinder
heads. Together with spacers and seals on the
camshaft cover fasteners, they also isolate the
covers from direct contact with the cylinder
heads, to reduce noise.
