TeraFlex Jeep JK 3.6L Crankcase Vent System Kits
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.
