The part load breather consists of an oil separator, a positive crankcase ventilation valve and a plastic pipe. The oil separator and the positive crankcase ventilation valve are installed in the top of the right (Bank 1) camshaft cover. The pipe connects the right camshaft cover to the inlet of the supercharger.
The oil separator is installed in a channel in the top of the camshaft cover. A baffle plate, which incorporates a gas inlet and an oil drain, is installed over the channel. The positive crankcase ventilation valve is installed on the outside of the camshaft cover and connected to the gas outlet from the channel to the pipe. The positive crankcase ventilation valve regulates the crankcase pressure and crankcase flow to optimize engine performance.
