The J&L JLT3070D-B 3.0 Driver Side Oil Separator is designed for 2018-2026 Jeep Wrangler models equipped with the 2.0L engine. During normal crankcase ventilation, oil vapor can travel through the intake system, where it may accumulate in the intake tube and manifold runners or reduce fuel octane. These effects can be more pronounced in forced-induction applications as crankcase pressure increases. This oil separator helps reduce the amount of oil vapor returning to the intake by capturing it before it can circulate through the system.
The separator is milled from solid billet aluminum for durable, long-term use and features a black anodized finish. Its removable, knurled tank base allows convenient draining, while the O-ring seal helps prevent leaks. Quick-connect PCV fittings support a straightforward installation and secure connection to the vehicle’s ventilation system. The compact tank is designed to hold up to 3 fluid ounces of collected oil and should be inspected and drained periodically based on driving conditions and engine use.
The J&L multistage filtration system combines a fine stainless steel mesh screen with an aluminum honeycomb filter. The screen captures fine oil vapors and allows them to condense, while the honeycomb media promotes additional separation so heavier oil droplets fall into the collection chamber. Cleaner air continues through the PCV system toward the intake. Regular maintenance, including draining the separator every 2,000 to 3,000 miles, helps maintain effective filtration and prevents the collection chamber from becoming full. This product is intended for automotive use and is not CARB approved.
