Is your exhaust gasket leaking? Before it explodes inside your vehicle, get a new one today.
Your car might look good on the outside, but if its exhaust pipes are leaking, then its style is for naught. Not only will exhaust leaks generate irritating noises, they'll also cause backfiring in the exhaust pipes. Because pipes are whole-piece tubes, the leaks most commonly come from the pipe connections. And what else are in those connections but gaskets? So if you don't want to be hassled, make sure each exhaust gasket is in good working condition.
Exhaust gaskets are usually made from asbestos, soft metal, or a combination of both. You can find them between the exhaust manifold and cylinder head, the manifold U-pipes and collector pipe, and the collector pipe and exhaust pipe. Unless they're welded and sealed permanently, such pipe junctions should have gaskets in them to ensure an airtight seal between pipes. Why is a leak-free seal important? It's because faulty sealing by the intake manifold sometimes ignites unburned fuel. That causes backfiring in the exhaust system, which is, of course, dangerous. Also, because exhaust gases flow forcefully, they create noise as they leak out through the fissures in the pipe connections.
So to prevent those leaks, you better junk those old and rusty gaskets and install new ones. A quality exhaust gasket won't cost you a fortune if you'll get it from a store that understands car owners like you. With no leak problems to pester you, you can then concentrate on making your ride even more visually appealing.
Important Facts You Need to Know About Exhaust Gasket
Why does your vehicle even need an exhaust gasket? Well, your vehicle is equipped with an exhaust gasket for a number of reasons. First, an exhaust gasket keeps the engine from working harder than it already has to. This gasket ensures that the engine doesn't waste power on pushing exhaust gases out of the cylinders. Second, the exhaust gasket keeps toxic gases safely contained within its structure. This prevents the leakage of exhaust emissions to other parts of the vehicle. And lastly, it completes the function of the exhaust system. All these functions support the operations of the engine system, so make sure that your vehicle's exhaust gasket is at its best. Should you need replacement units for your vehicle's stock exhaust gaskets, go for the performance exhaust gaskets at CarParts.com's catalogs. These aftermarket products are made to resist thermal pressure better!

• Delivers exhaust gases to the exhaust pipes
• Prevents back-pressure in the engine
Staying Leak Free: Replacing Your Exhaust Manifold Gasket
Your exhaust manifold is that series of adjoining metal tubes that collect the exhaust directly from your engine. It's designed so that each opening is connected to a corresponding engine exhaust port. Because your engine's exhaust is comprised of poisonous gases, it is very important to keep the exhaust system leak-free all the way to the point where your exhaust is treated by your catalytic converter and goes out through your muffler and tail pipe. If a leak occurs before reaching your catalytic converter, then you will have the serious problem of hot, deadly fumes being released into the atmosphere. Gaskets are durable, heat-resistant components that are fitted between your pipes to prevent these gases from prematurely escaping. When your exhaust manifold gasket gets damaged or worn out, you should replace it right away. With the right tools and basic mechanical skills, you can save money by doing it yourself.
Difficulty level: Moderate
Here's what you'll need:
- Wrench and socket set
- Penetrating oil
- Wire brush
- RTV sealant
- Replacement exhaust manifold gasket
- Replacement bolts and nuts
- Safety gloves and glasses
- Vehicle owner manual
Step 1: Open the hood of your vehicle and locate your exhaust manifold. Use your wrench and socket set to remove the bolts connecting your exhaust manifold to your engine. If the bolts seem to be firmly corroded into place, spray them with the penetrating oil and wait a few hours for the oil to do its work.
Step 2: Pull the exhaust manifold from your engine and remove the old gasket. Use your wire brush to scrape off any remaining gasket material that may be stuck to your exhaust manifold and your engine block.
Step 3: After you have removed all traces off the old gasket, use the rag to wipe down the mating surfaces of your engine block and exhaust manifold.
Step 4: Apply the RTV sealant to the mating surfaces of both your engine block and the exhaust manifold.
Step 5: Wait about half a minute for the sealant to get all sticky and pasty, then press your replacement exhaust manifold gasket over the exhaust manifold.
Step 6: Press the exhaust manifold firmly to the engine block. Make sure all the components are lined up properly.
Step 7: Secure the exhaust manifold to your engine block with nuts and bolts. If the old ones are no longer usable, replace them with new ones.
This shouldn't take more than an hour for an experienced DIYer. Refer to your vehicle owner manual for specific information that may require you to deviate from these general instructions.
