exhaust manifold for my car

Replace a Spare part Exhaust manifold – a defective one or if the limit of use has been already reached. Find out useful information about Exhaust manifold

• corrosion;
• mechanical damage and deformation of the manifold;
• normal wear and tear;
• deformation of manifold studs.

• strange noises in the engine;
• exhaust gas under the hood;
• increase in fuel consumption;
• the lambda probe readings;
• exhaust smell in the cabin.

• depressurization of the manifold;
• sudden changes in the part temperature;
• vibration and the lack of flexible joint;
• damage or wear of seals;
• damage to manifold mountings.

To assess the state of the exhaust manifold it is necessary to dismantle it. First the part geometry is checked, as well as presence of mechanical damage. Next, the tightness of fasteners. It is necessary to ensure the integrity of the system to prevent exhaust leakage. For more detailed diagnostics the part is checked on the stand and computer diagnostics is run.

Service life of cast-iron manifold is about 3 years. At the same time stainless steel manifolds with no mechanical damage can regularly work up to 7 years, because they do not corrode.

Minor damage and malfunctions can be resolved without having to install a new part. Small holes can be welded using a welding machine. Stainless steel parts in such case lose some of their properties and become more fragile. Milling is used to restore the original shape of the part. This kind of preventive maintenance allows to extend the part service life. If corrosion damage occurs, only manifold replacement is required.
