Going from point A to B has never been easier with a car. But driving day in and day out will result in a lot of parts wearing out. The exhaust gasket is one of these components. It's a mechanical seal that's placed between the exhaust manifold and engine. This part can appear thin or thick, depending on the application. Made either of organic heat-resistant material or metal composite, the gasket must be able to withstand extreme pressure and high temperatures.
Exhaust gaskets will eventually fail and you must replace them as soon as possible. The most obvious symptom is constant sputtering from an exhaust leak. To make matters worse, it's quite difficult to pinpoint the exact location of the leak; the only way to trace it is during hard acceleration. Obviously, you can't do this while your vehicle is parked. But there are ways and tools to quickly spot and correct the problem.
More often than not, the car exhaust gasket is the usual culprit, but the gaps between the catalytic converter flanges and rust holes in the muffler are also suspects. Replacing the gasket is the solution when you think the problem is at the exhaust manifold, and there are no visible cracks or holes. Before loosening the studs connecting the manifold to the cylinder head, let the engine cool down completely. If you have difficulty removing the studs, carefully apply oil to make it loose. For heavily corroded threads, it's best to rely on a professional mechanic.
If some resistance is encountered while removing the exhaust manifold, check if you need to remove additional brackets down the exhaust system. Once the manifold is out of the way, remove the old gasket and clean the mating surfaces before you install the new car exhaust gasket. Tighten it according to its torque specifications. It's best to apply some anti-seize compound on the hardware threads to fight corrosion and to make it easier when you remove the studs in the future. Once all hardware components are back in place, use a mechanic's stethoscope. This tool is used to isolate metallic sounds produced by different engine parts. For the exhaust, you should replace the solid probe section of the stethoscope with slender tubing-there should be no sound of rushing exhaust gases.
Because the simple exhaust gasket is put under high stress all the time, buy the best one you can afford without breaking your budget. Parts Train carries high-quality gaskets at reasonable prices. You just need your engine make and model information so that you can quickly search the right gasket for your exhaust manifold. The correct fit is essential to make the gasket replacement successful.
