The system consists of a fresh air hose from air cleaner to right cylinder head cover, a breather hose from left cylinder head cover, an orifice and a connection to intake system.
During idle or low speed operation, vapors are drawn through the orifice, into the idle air distribution tubes, then into the intake manifold.
