The J&L JLT3074P-B 3.0 Oil Separator helps reduce oil vapor buildup in the intake system of compatible 3.6L Dodge Durango and Jeep Grand Cherokee engines. During crankcase ventilation, oil vapor can travel through the PCV system and accumulate in the intake tube, manifold runners, and combustion system. This buildup can contribute to reduced intake cleanliness and may dilute fuel vapor, potentially lowering effective octane. Forced-induction engines can experience even greater crankcase pressure, but a quality oil separator can benefit any engine equipped with a PCV system.
The J&L Oil Separator 3.0 uses a solid billet aluminum body with a black anodized finish for durable service and a clean appearance. Its removable, knurled tank base makes draining simple, while the integrated O-ring seal helps prevent leaks. Quick-connect PCV fittings support a straightforward installation on the passenger side of compatible applications. The compact reservoir is designed to collect contaminants without requiring frequent service under normal operating conditions.
Inside, a multistage filtration system captures fine oil vapors while allowing cleaned air to continue through the intake system. A fine stainless steel mesh screen traps suspended vapor particles, and the aluminum honeycomb filter encourages those particles to combine and fall into the collection chamber. The separator holds up to 3 fluid ounces and should be checked and drained periodically; inspecting it every 2,000 to 3,000 miles is recommended. This J&L part is designed for select 2016-2026 Dodge Durango and Jeep Grand Cherokee models with the 3.6L engine. Verify vehicle fitment before installation. Not CARB approved.
