J&L Oil Separator

2016–2022 Jeep Grand Cherokee / 2016–2024 Dodge Durango 3.6L V6

Part #: 3074P-C

Overview

The J&L Clear Anod Oil Separator is a precision-engineered solution designed to enhance engine efficiency and longevity by effectively managing crankcase vapors. Specifically crafted for the passenger side PCV system on Jeep Grand Cherokee (2016–2022) and Dodge Durango (2016–2024) models equipped with the 3.6L V6 engine, this oil separator prevents oil vapors from entering and contaminating the intake system.

By capturing and separating oil from crankcase ventilation gases, it helps maintain cleaner intake components and preserves fuel octane levels, which is especially important for vehicles with forced induction or elevated crankcase pressures. This product is ideal for both enthusiasts and daily drivers seeking to reduce intake contamination, improve combustion efficiency, and extend engine life without sacrificing factory fitment or reliability.

Key Features

The J&L Oil Separator incorporates advanced filtration technology and durable construction to deliver reliable performance and ease of maintenance:

• Multistage filtration system traps fine oil vapors and condenses them into liquid form
• Fine mesh stainless steel screen captures microscopic oil particles
• 1/2" thick, 1/16" aluminum honeycomb filter enhances vapor separation efficiency
• 3-ounce fluid capacity collects separated oil before draining
• Clear anodized finish provides corrosion resistance and allows visual inspection of oil accumulation
• Solid billet aluminum construction ensures durability and strength
• Knurled tank base allows easy removal for draining accumulated oil
• O-ring seal guarantees leak-free operation under all conditions
• Quick connect PCV fittings enable straightforward installation and removal

Construction & Design

Crafted from a solid billet aluminum block, the J&L Oil Separator offers exceptional durability and resistance to heat and corrosion. The clear anodized finish not only protects the unit but also allows for quick visual checks of oil accumulation, making maintenance simple and efficient.

Inside, a fine mesh stainless steel screen captures the smallest oil vapors, while a dense aluminum honeycomb filter promotes the coalescence of oil droplets. This multistage design ensures that only clean air is routed back into the intake system, while heavier oil droplets collect at the bottom for easy drainage, preserving engine cleanliness and performance.

Installation & Fitment

The J&L Oil Separator is designed as a direct-fit replacement for the passenger side PCV system on Dodge Durango models from 2016 through 2024 and Jeep Grand Cherokee models from 2016 through 2022 equipped with the 3.6L V6 engine. Installation requires no modifications and utilizes quick connect fittings for a secure and hassle-free setup.

Routine maintenance involves draining the collected oil every 2,000 to 3,000 miles to maintain optimal performance and prevent buildup. This straightforward process helps ensure long-term reliability and engine protection.

Ideal For

This oil separator is perfect for owners of Dodge Durango and Jeep Grand Cherokee vehicles who want to reduce intake contamination, maintain fuel quality, and protect their engines from the adverse effects of oil vapor buildup. It is especially beneficial for vehicles equipped with forced induction systems, where crankcase pressures are higher and oil vapor accumulation is more pronounced.

Whether used for daily driving, towing, or spirited performance driving, the J&L Oil Separator helps keep your engine running cleaner and more efficiently, contributing to improved combustion and extended engine life.

J&L Oil Separator Co. builds application-specific oil catch cans (air/oil separators) designed to trap blow-by vapors before they contaminate intake and intercooler plumbing. It’s a practical performance upgrade for boosted and high-output engines, helping reduce carbon/oil buildup and keep intake charge paths cleaner over time.
