System Components

The crankcase vent oil separator removes vaporized oil from the blow-by vapors and returns the separated oil to the crankcase.

The crankcase pressure regulator controls the return of the blow-by pressure to the intake manifold through the crankcase vent oil separator hose.

The valve cover vent hose vents excessive crankcase pressure to the air cleaner and allows fresh air into the crankcase to prevent premature degradation of the engine oil.
