The J&L Oil Separator 3.0 Passenger Side, part number JLT3066P-C, helps protect the intake system of compatible 5.7L engines by capturing oil vapor from the crankcase ventilation system before it can collect in the intake tube, intake manifold runners, or dilute the fuel mixture. This concern is especially relevant on supercharged and turbocharged applications, where increased crankcase pressure can carry more oil vapor into the intake tract. Designed for the passenger side, this clear anodized separator provides a clean, durable solution for reducing oil contamination while allowing cleaner air to continue through the system.
The separator is milled from solid billet aluminum for dependable strength and features a knurled tank base for easier removal during service. An O-ring seal helps prevent leaks, while the multistage filtration system uses a fine stainless steel mesh screen to trap suspended oil vapor. Once collected particles become heavy enough, they fall into the removable reservoir and pass through an aluminum honeycomb filter that promotes additional vapor separation. This design helps keep separated oil out of the intake without restricting normal airflow.
With a 3-ounce fluid capacity, the J&L Oil Separator 3.0 is intended to be checked and drained periodically. J&L recommends servicing the separator approximately every 2,000 to 3,000 miles, although actual maintenance intervals may vary based on driving conditions and engine operation. The clear anodized finish provides a durable appearance and complements the solid billet construction. This automotive oil separator is designed for the passenger side of compatible 2011-2026 Dodge Durango 5.7L applications and is also listed for select Jeep Grand Cherokee fitments. Verify vehicle application and installation requirements before ordering.
