Positive Crankcase Ventilation Valve: Locations

(CCV LOCATIQN)

OPERATION

It meters the amount of crankcase vapors drawn out of the engine. The fixed orifice fitting is mounted in each of the valve covers in the rear of the engine.

When the engine is operating, fresh air enters the engine and mixes with crankcase vapors. Manifold vacuum draws the vapor/air mixture through the fixed orifice and into the intake manifold. The vapors are then consumed during engine combustion.
