The exhaust systems are built to withstand the high stress and heat conditions of an engine’s exhaust. But, they are still prone to corrosion and rust over time due to the exposure to high-stress conditions in your old car. So, over time a common problem with the exhaust system is a cracked exhaust manifold.
Visible cracks
One of the first symptoms of a cracked manifold is the appearance of visible cracks that get caught while inspecting the car. And to find the cracks, take a close look at the manifold and focus on the area where it is bolted to the engine. This area gets the first crack as it is subjected to most of the generated heat.
Extremely loud noises
Another common symptom of a problem with the exhaust is excessive noise. A cracked manifold will usually make unusual noises of any kind as some of the exhaust gasses are being forced out of the crack instead of out the exhaust. When the exhaust pipes or manifold break, they cause an exhaust leak which in turn, causes a noisy engine. This may be more pronounced when the engine is cold and first started and can be anything from a clicking noise to a more pronounced whistling or whooshing noise.
Decreased fuel efficiency
Performance issues are a common symptom of a problematic exhaust manifold. Since the manifold is an important component of the engine’s exhaust system and helps ensure that the engine receives the proper amount of backpressure, a cracked manifold can negatively impair engine performance.
Generally, the pipes become damaged or corroded, which results in an exhaust leak. Such a leak can cause the car to experience a decrease in power, ability to accelerate, and fuel efficiency due to the loss of backpressure.
