The Gates PCV valve for 2010–2018 Jeep Compass with the 2.4L four‑cylinder is a replacement crankcase vent valve intended to restore correct crankcase ventilation. It helps evacuate blow-by gases and maintain proper crankcase pressure; fitting a new valve returns the engine to its expected breathing behavior and is a recommended service when symptoms of valve failure appear.
