The part load breather comprises an oil separator, two PCV (positive crankcase ventilation) valves and a flexible hose. The oil separator and the PCV valves are installed in the top of the RH (right-hand) cylinder head cover. The flexible hose connects the RH cylinder head cover to the inlet of the SC (supercharger).
The oil separator is installed in a channel in the top of the cylinder head cover. A baffle plate, which incorporates a gas inlet and an oil drain, is installed over the channel. The two PCV valves are installed on the outside of the cylinder head cover and connected in parallel in the gas outlet from the channel to the flexible hose. The PCV valves prevent reverse flow into the cylinder head cover when there is minimal depression in the inlet of the SC.
