Oil-Air Separator RH 5.0L/5.2L Coyote

The Oil-Air Separator RH 5.0L/5.2L Coyote (MPN: M-6766-A50) is a critical emissions and engine management component engineered for Ford Coyote and Voodoo engine platforms in full-size trucks and Mustang models. This separator sits between the crankcase ventilation system and the intake manifold, preventing oil mist from entering the combustion chamber while maintaining proper crankcase pressure. Whether you're running a late-model F-150, F-250, or Coyote-powered Mustang, a functioning air-oil separator is essential for reliable operation, fuel efficiency, and compliance with engine specifications.

Constructed from durable OEM-spec plastic, the right-hand (RH) configuration channels crankcase vapors through a precision separator chamber that uses directional flow and coalescing surfaces to extract suspended oil droplets before they reach the intake. The 5.0L and 5.2L Coyote engines—known for high output and prolonged duty cycles in both stock and modified applications—demand reliable crankcase management to prevent carbon buildup and oil consumption issues. This genuine Ford unit measures 8.15 x 6.15 x 8.3 inches and weighs just 1.16 lbs, making it a direct bolt-on replacement that requires no modification to factory mounting points or hose routing.

Technicians, fleet operators, and performance enthusiasts benefit from keeping OEM air-oil separators in stock for routine maintenance intervals or emergency repairs. Failure symptoms—rough idle, increased oil consumption, or visible oil residue in the intake—demand immediate replacement to avoid downstream damage to valve seats and cylinder walls. Installation is straightforward: disconnect the hoses, remove the bracket bolt, and reverse the process with the new unit, typically taking under 30 minutes. Compatibility is confirmed for Ford Coyote and Voodoo engine variants across full-size truck and Mustang platforms equipped with this RH separator configuration.
