J&L Oil Separator
2012–2017 Jeep Wrangler 3.6L
3064D-C
Overview:
The J&L Clear Anodized Oil Separator is engineered to improve the performance and longevity of your Jeep Wrangler’s engine by effectively managing crankcase vapors. During normal operation, oil vapors can accumulate in the intake system, reducing fuel octane and potentially causing carbon buildup. This issue is especially pronounced in forced induction engines but is also relevant for naturally aspirated engines like the 3.6L V6 found in Jeep Wranglers from 2012 to 2017.
Designed specifically for the passenger side of the Jeep Wrangler, this oil separator captures and separates oil vapors from the crankcase ventilation system before they reach the intake manifold. By doing so, it helps maintain cleaner intake air, preserves fuel quality, and reduces engine deposits, contributing to smoother operation and improved reliability.
Key Features:
The J&L Oil Separator incorporates advanced filtration technology and durable construction to deliver reliable performance:
- Multistage filtration system with a fine mesh stainless steel screen to trap fine oil vapors
- 1/2" thick, 1/16" aluminum honeycomb filter that coalesces oil droplets for efficient separation
- 3-ounce fluid capacity tank to collect separated oil, minimizing reintroduction into the intake
- Clear anodized finish for corrosion resistance and visual inspection of fluid level
- Solid billet aluminum construction for strength and durability
- Knurled tank base allows easy removal for draining collected oil
- O-ring seal ensures a leak-free installation
- Quick-connect PCV fittings for straightforward hookup
- Designed specifically for the passenger side of 2012–2017 Jeep Wrangler models with 3.6L engines
Construction & Design:
Crafted from solid billet aluminum, the J&L Oil Separator is built to withstand the rigors of daily driving and off-road conditions. The clear anodized finish not only protects against corrosion but also allows for quick visual checks of the oil level inside the separator. The internal filtration system combines a fine stainless steel mesh with a precision-machined aluminum honeycomb filter, maximizing oil vapor capture while allowing clean air to flow freely back into the intake system.
The separator’s tank holds up to 3 ounces of oil condensate, which is more than sufficient given the typical amount of oil vapor generated by the PCV system. The knurled base design makes routine maintenance simple, enabling you to drain the collected oil every 2,000 to 3,000 miles without hassle.
Installation & Fitment:
Installation of the J&L Oil Separator is straightforward and requires no permanent modifications to your Jeep Wrangler. It is designed to fit the passenger side PCV system on 2012–2017 Jeep Wrangler models equipped with the 3.6L engine, including Sport, Sahara, Rubicon, and 75th Anniversary editions, both standard and Unlimited variants.
The unit connects directly to existing PCV hoses using quick-connect fittings, making it a clean and efficient upgrade. Regular draining of the separator is recommended to maintain optimal performance and prevent overflow.
