Cracked Exhaust Manifold Repair Kit

An engine’s exhaust manifold (or manifolds) is an integral part of the exhaust system. The manifold is bolted to the engine’s head and is the first component that spent exhaust gasses are routed through on their way out of the exhaust system. Unfortunately, manifolds often develop stress cracks from the extreme heat that they are subjected to. As the porous metal that most manifolds are made of expands and contracts with temperature changes, cracks can occur. Below are the symptoms of a cracked exhaust manifold.

Visible Cracking

1. When you have cracked exhaust manifold, it might be possible to repair it rather than spend money on a new one. Taking it to a repair shop could cost you quite a considerable amount for labor and parts, so trying a repair yourself first can be a good option. However, most exhaust manifolds are made.

3. Nov 25, 2015  What Causes an Exhaust Manifold to Crack or Leak? By Valerie Johnston on November 25, 2015. If your exhaust manifold is cracked or leaking, the back pressure in the exhaust system will be incorrect, which can reduce engine power, cause sputtering and other problems.

4. Cracked Exhaust Manifold. A cracked or broken exhaust manifold is most often caused by one of two things. The first reason is heat cycles and/or age. Over time, the manifolds just can't take the heat anymore (literally and figuratively), and cracks begin to form in them. The cracks then turn into small holes, and it doesn't get any better from.

One symptom of a cracked manifold will be a visible crack that you can see on the manifold's surface. To look for a crack, look closely at the manifold, particularly where it bolts up to the motor and where the most heat will be. A large crack will be relatively easy to spot, but a smaller, hair-line fracture might be more difficult to locate. You may need to remove the manifold from the engine bay to inspect the entire surface.

Symptoms of a Cracked Exhaust Manifold by William Zane. An engine’s exhaust manifold (or manifolds) is an integral part of the exhaust system. The manifold is bolted to the engine’s head and is the first component that spent exhaust gasses are routed through on their way out of the exhaust system. A cracked manifold will usually make. The exhaust systems starts at the exhaust manifold gasket and travels through the exhaust manifold, header pipe, catalytic converter, mufflers or resonators and out the exhaust pipe. Cracked exhaust manifolds are one of the more serious leaks since they receive the initial combustion gases from the cylinders. A competent DIY repair person can.

Excess Noise

A cracked manifold will usually make unusual noises of some kind as some of the exhaust gasses are being forced out of the crack instead of out the exhaust. 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. With the vehicle running, open the engine cover and listen near the exhaust manifolds to see if there is any unusual noise.

Exhaust Odors

Manifold cracks can also cause excessive exhaust odors since a portion of the exhaust gasses are evacuating out of the crack instead of out the end of the tail pipe. The exhaust smell may or not be noticeable from the interior of the vehicle but will be more noticeable in the engine bay and the areas around the manifold. Exhaust leaks are potentially harmful to the health of the car’s occupants.

Loss of Performance

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 (the pressure developed by the exhaust system as gasses are evacuated), a cracked manifold can negatively impair engine performance. A crack is, in essence, a vacuum leak and may prevent all of the engine functions from operating correctly.

Your car has two manifolds – an intake manifold and an exhaust manifold. Both serve essential purposes, but the one most likely to experience problems over the long term is the exhaust manifold. Depending on your make and model, your manifold might be a single piece of cast iron with channels/ports built into it, or it could be a collection of pipes tied together. The basic job of the exhaust manifold is to take the gases from each cylinder and send them to the exhaust pipe.

Why manifolds crack and leak

As you can imagine, exhaust manifolds are subject to intense heat. They’re also subjected to considerable expansion and contraction as they heat up and cool back down. Over time, this leads to metal fatigue (both cast iron and other types of exhaust manifolds are subject to this). As the fatigue becomes worse, it’s possible for the manifold to develop cracks.

Another potential problem lies with the exhaust manifold gasket. The gasket sits between the manifold and the engine block, and is designed to seal the small gap that exists between these two components. Like the manifold itself, the gasket is subjected to significant heat, as well as expansion and contraction. It will eventually fail (this is normal, and cause by nothing more than general wear and tear). When it fails, it will begin to leak.

Problems associated with manifold cracks and leaks

There are several problems created with exhaust manifold cracks and leaks. First, hot exhaust gases are now being vented under the hood, rather than being sent downstream through the exhaust pipe. This can damage plastic components in the engine bay. It can also become a health hazard, as the exhaust fumes can enter the car’s cabin.

There’s also the possibility that it will affect engine performance. If your exhaust manifold is cracked or leaking, the back pressure in the exhaust system will be incorrect, which can reduce engine power, cause sputtering and other problems. Of course, you won’t pass emissions testing, either.
