TeraFlex 4839100 Crankcase Vent System Kit for Jeep Wrangler JK 3.6L Pentastar

The TeraFlex Crankcase Vent System Kit (CVS) prevents engine oil from being drawn into the intake manifold by engine vacuum during extreme off-road inclines and declines. Designed specifically for 2012-2018 Jeep Wrangler JK models with the 3.6-liter Pentastar V-6 engine, this kit adds a second PCV valve to the front of the engine via an oil fill cap adapter and T-fitting.

Why You Need This Kit:

On steep inclines and declines, engine oil flows to the rear or front of the engine and valve covers. At extreme angles, the factory single PCV system allows engine vacuum to draw oil through the PCV valve and into the intake, where it enters the combustion chamber. This causes exhaust smoke from burning oil and can potentially lead to hydrolocking and serious internal engine damage.

How It Works:

By adding a second PCV valve at the opposite end of the engine, this system ensures that only air is allowed to enter the crankcase vent system regardless of engine orientation while off-roading. This dual-valve design maintains proper crankcase ventilation without allowing oil ingestion at any angle.

Kit Includes:

• Oil fill cap to crankcase vent adapter
• PCV valve
• High-quality hoses
• All necessary mounting hardware for complete installation

• 2012-2018 Jeep Wrangler JK (2-door) with 3.6L Pentastar V-6
