J&L Oil Separator 3.0 PCV Oil Catch Can for F-150/Expedition Passenger Side (Black) — Stainless Mesh, Drainable Tank

J&L Oil Separator Co. 3.0 is a passenger-side PCV oil catch can designed to reduce oil vapor ingestion in 2011–2026 F-150 2.7L/3.5L engines and 2018–2021 Expedition 3.5L, providing a cleaner intake tract and easy maintenance.

Built to be a direct replacement for the factory passenger-side oil separator, this J&L 3.0 unit captures oil mist before it reaches the intake system. Its stainless fine-mesh filter traps oil vapors and releases them when droplets become heavy enough to return to the tank, minimizing crankcase vapor transfer while remaining simple to install and service. The kit ships with a knurled drain base, O-ring sealing, and clear plug-and-play instructions including video guidance.

How does this oil separator help my F-150 or Expedition?

The J&L 3.0 reduces the amount of oil-laden vapor entering the intake, helping keep throttle bodies, intake runners, and intercoolers cleaner over time. It doesn't alter engine calibration; instead it acts as a filtration and capture device between the crankcase and intake. That cleaner intake environment can lead to more consistent performance and easier maintenance.

• Traps fine oil mist with stainless steel mesh filter.
• Returns accumulated oil to drainable tank base to prevent ingestion.
• Mounts in factory passenger-side location for OEM fitment.

Is installation difficult for a home mechanic?

Installation is intended to be plug-and-play with factory hoses and hardware in most applications, so experienced DIYers can typically complete it with basic hand tools. J&L includes video instructions to walk through removal of the stock separator and installation of the 3.0 unit. No engine reprogramming is required.

• Uses factory connections for straightforward replacement.
• Video instructions included to simplify each step.
• No special tools or ECU changes needed.

What maintenance does the J&L 3.0 require?

Routine maintenance consists of periodically draining the tank and inspecting the stainless mesh filter for heavy buildup. The knurled tank base unscrews easily for quick oil removal and the O-ring seal prevents leaks when reassembled. Follow vehicle-specific service intervals or inspect during regular oil changes.

• Hand-drainable knurled base for quick oil removal.
• O-ring seal to prevent seepage between services.
• Inspect mesh filter during service intervals for cleaning or replacement.

Who is this for: Drivers and technicians who own 2011–2026 Ford F-150s with 2.7L or 3.5L engines, and 2018–2021 Expeditions (passenger side), and want a factory-fit oil separation solution to reduce intake contamination without complicated installation. It's suited to owners who prefer a washable stainless filter, easy draining, and a US-made product that integrates with the stock PCV plumbing.
