Jeep Wrangler JL 2018-2026 & Gladiator JT 2020-2026 3.6L, TeraFlex Crankcase Vent System Kit

Steep climbs send engine oil to the rear of the engine and valve covers. At extreme angles the factory PCV system lets engine vacuum draw that oil into the intake, which causes exhaust smoke and can hydro lock the engine.

The TeraFlex Crankcase Vent System adds a second PCV valve to the front of the engine through an oil fill cap adapter and T-fitting, so only air enters the vent system regardless of engine orientation. A ball check valve system keeps oil out of the intake.

Install the adapter, valve and hoses, and the engine breathes properly when the trail points up.
