Cast Iron Exhaust Manifold Repairs
Remanufacturing can save up to 75% of the cost of a new replacement component.
A car’s exhaust manifold is a robust and integral part of the engine. Its purpose is to collect exhaust gases from the cylinders and direct them towards the exhaust system, away from the engine. Exhaust gas is toxic and hot, meaning the components of the exhaust manifold must be durable and capable of being exposed to high temperatures. Since the early 20th century, cast iron has been the material of choice to produce heavy engine parts like engine blocks, cylinder heads and exhaust manifolds due to its excellent castability, extreme compression strength and good heat resistance.
If you have a damaged exhaust manifold in a vintage motor, look no further than the heritage restoration team here at Cast Iron Welding Services to lend their expert hands. We are scrupulous when it comes to restoration and detailing, going to great lengths to match the repaired item as closely as possible to the original.
Signs of a Damaged Exhaust Manifold
Cast iron is highly durable and can withstand extreme temperatures and wear and tear. However, over time, it can deteriorate through corrosion and fatigue. Repeated heat cycles over many years cause the metal to crack and warp, which can lead to exhaust fumes leaking into the engine. If you think you may have a damaged manifold, contact the team at Cast Iron Welding Services for an informal chat and to discuss repair options.
Securing the longevity of your classic car, means regular maintenance and lots of TLC. It’s wise to inspect the major engine components regularly for corrosion and wear and tear. Look out for strange noises, or if you notice the engine is running louder. A leaky manifold will also affect the engine performance, so you may notice a drop in fuel efficiency as well. Reduced engine power can also be an indicator that the exhaust manifold is damaged.
Classic Car Exhaust Manifold Repair
A classic car exhaust manifold is exposed to extreme heat and cooling multiple times every day as the engine is switched on and off. This extreme heat causes the metal to expand slightly, then contract as it cools down. Over time, this regular expansion and contraction can cause the metal to fail and develop cracks. Thermal stress and corrosion are the main reasons to repair a cast iron component.
Making the decision to repair rather than replace a vintage cast iron exhaust manifold is an easy one for many classic car owners. Importantly, maintaining an original part means retaining its authenticity. And as with any cast iron restoration project, replicating the original is extremely important to the team here. Re-fitting original parts preserves the vehicle’s original characteristics, including its sound and weight, and components fit better within their original casings and environment. The Cast Iron Welding Services team has a wealth of heritage restoration experience. Using our industry-leading gas fusion welding process, we have been repairing valued, treasured items up and down he county from bandstands to finials.
