Engine Crankcase Breather Hose – Oil Reservoir to Air Filter Housing Engine Timing Cover Seal air conditioningEngine Crankcase Breather hoses are part of a vehicles Positive Crankcase Ventilation (PCV) system. The job of the PCV system is to allow pressure to escape from the crankcase in a controlled manner. It is necessary to vent the crankcase of positive pressure caused by engine blow by (gas from the combustion event that leaks past the pistons.) This blow by gas is routed back into the intake air stream thereby reducing the emission of unburned
