J&L Black Anodized Oil Separator Driver Side: Jeep Wrangler 2018-2024

J&L Oil Separator

2018–2024 Jeep Wrangler 2.0L

3070D-B

Overview:

The J&L Black Anodized Oil Separator is engineered to improve the crankcase ventilation system on Jeep Wrangler models from 2018 through 2024 equipped with the 2.0L engine. Designed to trap and separate oil vapors from the crankcase gases before they re-enter the intake system, this oil separator helps maintain engine performance and fuel quality by preventing oil contamination in the intake manifold and fuel mixture. Ideal for both naturally aspirated and forced induction applications, it reduces intake deposits and preserves octane levels, ensuring cleaner combustion and improved engine longevity.

Built for Jeep enthusiasts who demand reliability and efficiency, this oil separator is a direct-fit, driver side replacement that enhances the factory PCV system without requiring modifications.

Key Features:

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

• Multistage filtration system with a fine mesh stainless steel screen to trap microscopic oil vapors
• 1/2" thick, 1/16" aluminum honeycomb filter that coalesces oil droplets for effective separation
• 3-ounce fluid capacity to collect and hold separated oil, minimizing intake contamination
• Knurled tank base for easy removal and draining of accumulated oil
• 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 for corrosion resistance and a sleek appearance
• Solid billet aluminum construction for strength and durability under harsh conditions

Construction & Design:

Crafted from solid billet aluminum, the J&L oil separator offers exceptional durability and resistance to heat and corrosion. The black anodized finish not only protects the unit but also complements the engine bay aesthetics. The internal 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. The removable base with a knurled grip facilitates routine maintenance by enabling easy draining of collected oil without disassembly.

Installation & Fitment:

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