Exhaust Manifold Gasket Replacement
How are exhaust manifold gasket issues diagnosed?
Identifying an exhaust manifold gasket leak can be very easy if ticking is present, and plenty of exhaust gas is making a stink at the engine, but minor leaks can be tricky. Ordinarily, the vehicle will be raised, and the intake manifold will be inspected for signs of leakage, such as black marks, and burned non-metallic components around the exhaust manifold. If there are no signs, the exhaust may be smoke tested, or plugged to make leaks more apparent.
How is an exhaust manifold gasket replaced?
Exhaust manifold gasket replacement only requires the manifold retaining hardware to be removed, the old gasket removed, and all mating surfaces cleaned thoroughly. If the manufacturer specifies sealant, it is applied to the gasket, otherwise the gasket is placed on the exhaust studs. The exhaust manifold will slide in place on the gasket, and the technician will torque new exhaust manifold retaining fasteners to factory specification.
