  Gasket Exhaust Manifold

• Description:

  This is the Genuine Ford exhaust manifold gasket for F-150, Expedition, and Navigator applications. It is also referred to as an exhaust flange gasket in some catalogs and serves as the sealing element between the exhaust manifold and the next downstream component, typically the turbocharger inlet or the exhaust pipe flange. Construction is a metal-core gasket with a high-temperature compound rated for the exhaust stream and the cyclic clamping load of the flange. A leaking exhaust manifold gasket is a frequent cause of cold-start exhaust tick that softens as the metal expands and seals at temperature, of unburned air entering the upstream oxygen sensors, and of fuel trim drift that the controller cannot correct without an exhaust leak repair. This OEM gasket is the correct service item for the JL3Z manifold family. Install with the mating flanges clean and flat, use fresh studs and nuts as recommended where the original hardware is heat-discolored, follow the Ford-published torque value, and verify no exhaust leak with the engine warm before returning the truck to service.
