Oldsmobile Exhaust Manifold

Your vehicle's Exhaust Manifold(s) play a major role in not only the exhaust system for your car or truck, but also the safety of its occupants. The exhaust manifold is the first component of the exhaust system. A broken or damaged Exhaust Manifold will not only fail most state safety and emission inspections, it could also potentially allow harmful exhaust gasses into the passenger compartment of your vehicle. Your Exhaust Manifold takes the exhaust gasses from all of the individual combustion chambers in your engine and combines them to one outlet to flow through the rest of the exhaust system.

Common reasons for exhaust manifold failure include: improper engine tuning, over heating, age, corrosion, and general wear and tear. Therefore, the quality of the design and material is important to the reliability of the Exhaust Manifold.

Replacement exhaust manifolds from 1A Auto are of the highest quality. Our new aftermarket exhaust manifolds last on average 2-3 times longer than used OEM manifolds. Our exhaust manifolds are engineered with improvements over the original designs, fixing known faults.

Tips on how to replace an Exhaust Manifold:

• Obtain a copy of the dealer service manual procedure.
• Many dealer customer service or parts counters will let you copy this information if you ask nicely. Some may charge for it, but either way having the correct procedure and diagrams is invaluable.
• Understand how Exhaust manifold mounts and what it mounts to.
• Most exhaust manifolds have 2 main attachment points
• Exhaust Manifold to cylinder head (upper)
• Exhaust Manifold to Catalytic converter or intermediate pipe (lower)
• Choose an appropriate work area and have patience.
• Make sure you have a large protected space to work in.
• Don't let yourself be rushed by the weather.
• The day before, or hours before disassembly it is a good idea to spray the mounting bolts & nuts with a penetrating spray to make removal easier.
• If available take pictures of the manifold before you begin. These pictures can be a valuable resource during reassembly.
• Allow yourself plenty of time.
• An Exhaust Manifold replacement can be a day long project.
• Don't let yourself be rushed by starting at 7 pm on Sunday knowing you need the car for work at 6 am on Monday.

Other things you may find attached to your Exhaust manifold are:

• Emissions or A.I.R. tubes going to an air pump, Catalytic converter or EGR valve
• Heat Riser Valve. On some exhaust systems you many have a heat riser valve between the bottom flange of the manifold to the intermediate pipe. You will need to reuse this valve for the emissions system.
