On steep inclines/declines, engine oil flows to the rear/front of the engine and valve covers. At extreme angles, the factory PCV system allows engine vacuum to draw oil through the PCV valve and intake into the combustion chamber. This causes exhaust smoke from the burning oil and possibly hydro-locking the engine, as well as other internal damage. TeraFlex Jeep JK 3.6L crankcase vent system kits prevent oil from being drawn into the intake by engine vacuum while driving on extreme inclines. The kits add a second PCV valve to the front of the engine via an oil fill cap ada
