J&L Oil Separator

2018–2024 Jeep Wrangler 2.0L Turbo

Part #: 3070D-B

Overview

The J&L Black Anodized Oil Separator is a precision-engineered upgrade designed specifically for Jeep Wrangler models equipped with the 2.0L turbocharged engine from 2018 through 2024. This oil separator enhances the crankcase ventilation system by efficiently trapping and separating oil vapors from the crankcase gases before they re-enter the intake system. By preventing oil contamination in the intake manifold and fuel mixture, it helps maintain optimal engine performance, fuel quality, and combustion cleanliness.

Ideal for Jeep enthusiasts who demand reliability and efficiency, this direct-fit driver side replacement integrates seamlessly with the factory PCV system without requiring any modifications. Whether your Wrangler is naturally aspirated or equipped with forced induction, the J&L oil separator reduces intake deposits, preserves octane levels, and supports longer engine life.

Key Features

J&L’s oil separator incorporates advanced filtration technology and durable construction to deliver superior performance and reliability:

• Multistage filtration system featuring a fine mesh stainless steel screen to capture microscopic oil vapors
• 1/2" thick, 1/16" aluminum honeycomb filter media that coalesces oil droplets for effective separation
• 3-ounce fluid capacity tank to collect and hold separated oil, minimizing intake contamination
• Knurled tank base for easy removal and draining of accumulated oil without disassembly
• O-ring seal ensures a leak-free connection within the PCV system
• Quick-connect PCV fittings for straightforward installation and secure hose attachment
• Black anodized finish provides corrosion resistance and a sleek engine bay appearance
• Solid billet aluminum construction for strength and durability under harsh operating conditions

Construction & Design

Crafted from solid billet aluminum, the J&L oil separator offers exceptional durability, heat resistance, and corrosion protection. The black anodized finish not only enhances longevity but also complements the engine bay’s aesthetics. Internally, the filtration media combines a fine stainless steel mesh with a precision-machined aluminum honeycomb structure engineered to maximize oil vapor capture while allowing clean air to flow freely back into the intake system.

The removable base features a knurled grip, enabling easy draining of collected oil during routine maintenance without the need for full disassembly, ensuring hassle-free upkeep and sustained performance.

Installation & Fitment

This oil separator is designed as a direct replacement for the driver side PCV oil separator on Jeep Wrangler 2.0L turbo models from 2018 to 2024. 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 overflow.
