1986-1993 Mustang J&L 3.0 Oil Separator Passenger Side - Black

Prevent harmful oil vapor from entering the intake runners of the 5.0 engine in your 1986-1993 Mustang with this black anodized, passenger side J&L 3.0 oil separator! During this venting process, large amounts of oil in the form of vapors can coat the intake manifold which dilutes your air-fuel ratio, lowering its octane level. This oil separator is designed to counteract the oil vapors thanks to the multi-stage filter system. The multi-stage traps within this catch can consist of a fine mesh stainless steel screen to prevent fine oil vapors from passing through an aluminum honeycomb filter where the oil is drained into the base of the catch can tank. The tank holds 3 oz of fluid and while that may not sound like a lot, you should never see that much oil in your PCV system. Drain the tank every oil change and you will never come close to filling it. Enhance the engine performance in your 1986-1993 Fox Body Mustang and eliminate harmful oil vapors from your intake manifold!

What Is An Oil Separator?

An oil separator is installed in a vehicle's crankcase ventilation system that captures oil mist and other contaminants before they can re-enter the engine's intake system. By separating oil from the air flowing through the Positive Crankcase Ventilation (PCV) system, it helps keep the intake tract, intercooler, and intake valves cleaner.

Why Should I Install An Oil Separator On My Fox Body?

Installing an oil separator can help reduce carbon buildup, minimize oil contamination in the intake system, and maintain engine performance over time. An oil separator can also help improve long-term engine cleanliness and reduce maintenance related to excessive oil accumulation.

How Often Should I Drain My Oil Separator?

Drain intervals vary depending on driving conditions, climate, engine type, and vehicle usage. As a general guideline, inspect the oil separator after the first few hundred miles to understand how much oil your vehicle collects, then establish a routine based on those findings. Many owners check and drain the separator during regular oil changes, while vehicles driven in cold weather, under heavy load, or on track may require more frequent servicing. Always avoid allowing the reservoir to become completely full.
