TeraFlex Crankcase Vent System Kit – 4839200

The TeraFlex JL / JT 3.6L Crankcase Vent System Kit (CVS) prevents oil from being drawn into the intake by engine vacuum while driving on extreme inclines/declines. This kit adds a second PCV valve to the front of the engine via an oil fill cap adapter and T-fitting. Adding a second PCV valve at the opposite end of the engine ensures only air is allowed to enter the crankcase vent system regardless of engine orientation while off-roading.

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 and other internal damage.

EPA LEGAL: TeraFlex Crankcase Vent System Kit (CVS) meets the EPA Anti-Tampering Policy reasonable basis for emissions criteria and can be sold in U.S. states which don’t require a California Air Resources Board (C.A.R.B) Executive Order (E.O.) for aftermarket, performance and add-on parts.
