J&L Oil Separator

2012–2017 Jeep Wrangler JK 3.6L V6

Part #: 3064D-C

Overview

The J&L Clear Anodized Oil Separator is a precision-engineered solution designed to enhance the performance and durability of your 2012–2017 Jeep Wrangler JK equipped with the 3.6L V6 engine. By effectively managing crankcase vapors, this oil separator prevents oil vapor buildup in the intake system, which can degrade fuel octane and promote carbon deposits. While especially critical for forced induction engines, this product also benefits naturally aspirated engines like the Jeep’s 3.6L by maintaining cleaner intake air and reducing harmful engine deposits.

Specifically designed for the passenger side PCV system, the J&L Oil Separator captures and separates oil vapors before they reach the intake manifold. This results in improved engine reliability, smoother operation, and helps preserve fuel quality over time, making it an essential upgrade for Jeep Wrangler owners who demand both daily dependability and off-road capability.

Key Features

The J&L Oil Separator combines advanced filtration technology with durable construction to deliver consistent, long-lasting performance:

• Multistage filtration system featuring a fine mesh stainless steel screen to trap microscopic oil vapors
• 1/2" thick, 1/16" aluminum honeycomb filter that efficiently coalesces oil droplets for superior separation
• 3-ounce fluid capacity tank designed to collect separated oil and minimize reintroduction into the intake
• Clear anodized finish provides corrosion resistance and allows easy visual inspection of fluid levels
• Solid billet aluminum construction ensures strength and durability under harsh driving conditions
• Knurled tank base enables quick and simple removal for draining collected oil
• O-ring seal guarantees a leak-free installation
• Quick-connect PCV fittings facilitate straightforward, clean hookup without permanent modifications
• Engineered specifically for the passenger side PCV system on 2012–2017 Jeep Wrangler JK 3.6L models

Construction & Design

Crafted from solid billet aluminum, the J&L Oil Separator is built to withstand the demands of both daily driving and rugged off-road use. The clear anodized finish not only resists corrosion but also allows for quick visual monitoring of the oil level inside the separator, helping you maintain optimal performance with ease.

Internally, the separator features a dual-stage filtration system combining a fine stainless steel mesh with a precision-machined aluminum honeycomb filter. This design maximizes the capture of oil vapors while allowing clean air to flow freely back into the intake system, reducing carbon buildup and preserving engine efficiency.

The integrated 3-ounce tank capacity is ample for typical PCV system oil vapor output, and the knurled base design simplifies routine maintenance by enabling easy draining every 2,000 to 3,000 miles.

Installation & Fitment

Installation is straightforward and requires no permanent modifications to your Jeep Wrangler. The unit is designed to fit the passenger side PCV system on all 2012–2017 Jeep Wrangler JK models equipped with the 3.6L V6 engine, including Sport, Sahara, Rubicon, and 75th Anniversary editions, in both standard and Unlimited variants.

The oil separator connects directly to existing PCV hoses using quick-connect fittings, ensuring a clean, efficient upgrade. Regular draining of the collected oil is recommended to maintain peak performance and prevent overflow.
