This guide will provide everything you need to know, from its healthy function to replacing faulty items. An exhaust manifold gasket is a mechanical seal that is usually made from multi-layered embossed steel. However, it can be manufactured from high-temperature fiber material, graphite, ceramic composites, and combinations of those materials too.
However, some engines, like a V6 or V8 will require two. This is something all workers and personnel within the automotive industry should know.
As mentioned, the gasket connects the manifold to the cylinder head. The exhaust manifold gasket simply encourages a better performance over time by covering the seal and stopping leaks, which can also cause temperature spikes.
The exhaust manifold gasket helps ensure that the car drives more smoothly and with greater power. It is an especially valuable component when the engine needs to work hard.
Faults with the exhaust manifold gasket are usually, although not always, attributed to general wear and tear. As such, it is an issue that tends to impact older vehicles rather than new cars with low mileages. As with most vehicle faults, regular servicing is a good way to identify potential problems before they escalate or take a toll on other parts of the vehicle.
However, you can also tell that the exhaust manifold gasket requires a replacement due to the following symptoms:. The exhaust manifold gasket is responsible for covering the intersection between the cylinder and the manifold unit. So, as soon as a problem surfaces, leakage will occur. The first, and most obvious, sign of this happening comes courtesy of an audible hissing, spitting, or tapping sound. It is a sound that will worsen if the situation is left untreated.
While loud noises can be attributed to many car faults, the type of sound and situations that it occurs are clear giveaways. Leaks caused by faulty exhaust manifold gaskets are only of the potential causes. Even so, it is one that is worth investigating, particularly if accompanied by other issues. After all, poor fuel efficiency will result in a steep increase in weekly fuel costs. Most people respond to this right away, often by contacting experts like you to identify the issue. Again the issue will worsen over time.
However, it should be noticeable pretty quickly after the faults occur. A burning smell is another symptom that often surfaces as a result of leaking gas caused by faulty exhaust manifold gaskets. The smells occur because the heat causes other components, such as plastics or engine wiring, to burn and melt.
If the burning smells come from the engine bay, the manifold gasket could be the root cause. Very few drivers, consumers or workers, will ignore burning smells due to their worrying nature.
By treating the primary issue quickly, it can reduce the level of damage caused to the other components while also delivering peace of mind.

So position or line up the gasket and make note of which way the gasket must be turned to achieve that. On some openings the raised portion will face the head on others it will face the manifold.
Only the center double gasket could be the same for each side. I don't think it matters but on that one I usually face the lip toward the manifold. Comment Post Cancel.
Thanks, It is a V I can make the gaskets square up on the manifold with the bead in either direction. I will install them with the bead to the manifold side and the pipe side below the heat riser valve and hope for the best. Thanks again, Steve. Originally posted by wolfie View Post.

Different nameplates use different nomenclature in their OE service manuals for directional markings; for consistency in leveraging repair information, Fel-Pro works to follow the nameplate reference. This can be confusing, especially when dealing with a transversely-mounted engine, which most front wheel drive vehicles have.
The answer is quite simple though — the front of the engine is the end where the drive belts are located. If you were to install your gaskets on the left and right side based on looking at the engine from the front of the vehicle, the gaskets would be incorrectly installed. The UP stamp is found on Fel-Pro head gaskets for Subaru engines, which have horizontally opposed cylinders. The edge of the gasket with the Up stamp must be kept up toward the top of the engine block.
In these cases, it does not matter which direction the gasket is installed. If it were crucial, it would be marked. There are no directional markings on the gaskets. Water outlet and thermostat gaskets can be installed with the striping facing either direction, as long as there no directional indicators.
If there are bypass holes, the gasket must be installed in the correct orientation to allow coolant flow. When installing Fel-Pro exhaust manifold gaskets, if there is a smooth, metallic side and a composite side, the metallic side should be installed facing out, meaning toward the exhaust manifold.
