How did we estimate these prices?

Jerry's experts researched and collected data from 2500+ real repair shops in all 50 states in the US, including everything from the total cost of repair services to the hourly labor cost for mechanic labor in each shop. We combined that data with our expert database of hundreds of real repair jobs, thousands of real cars, millions of real car part prices in order to best estimate the cost of each repair service. Our labor cost estimate is calculated by taking the average hourly labor rate for a certified mechanic in the US, times the number of hours it takes on average to complete a repair. We recommend you compare your local shops with Jerry and contact those shops directly to get final pricing for your vehicle.

What parts do I need for my exhaust manifold gasket replacement and how much do those parts cost?

Each vehicle will require unique parts for an exhaust manifold gasket replacement. You can check your owner’s manual or consult with a mechanic, but in general, you’ll need the following components:
  1. Exhaust manifold gasket(s): The exhaust manifold gasket seals the exhaust manifold to the engine’s cylinder heads, which prevents exhaust gas leaks. This part typically costs $15 to $50.
  2. Exhaust manifold studs and nuts: Studs and nuts are commonly used to secure the exhaust manifold to the engine’s cylinder heads. It's always recommended to change these studs and nuts if your exhaust manifold or gaskets are being replaced. Exhaust manifold studs and nuts cost $25 on average.
  3. Cylinder head ports: If your exhaust manifold gasket is damaged from high temperatures, your cylinder head ports may be burned as well. Your mechanic will need to remove the cylinder heads and repair the ports, which can vary in cost. 
  4. Exhaust flange gasket : A flange gasket is sometimes used to connect the exhaust manifold and exhaust pipe. A replacement flange connection will cost $15 to $25.
  5. Anti-seize compound: To prevent the exhaust manifold studs and nuts from seizing, your mechanic may use an anti-seize compound. Anti-seize compounds usually cost $30.
You can purchase exhaust manifold gasket parts for your car from auto parts stores like AutoZone, NAPA Auto Parts, and Advance Auto Parts, as well as online retailers such as Amazon and RockAuto. Three brands we recommend for Exhaust Manifold gasket parts are Fel-Pro, Victor Reinz, and MAHLE Original. However, the right parts and brands for your exhaust manifold gasket are dependent on your vehicle’s year, make, and model.
For exhaust manifold gaskets, it's best to opt for OEM parts. While aftermarket parts may be cheaper, OEM parts are more durable and tend to last longer. OEM parts may also come with warranties, which can come in handy if you ever need to change your exhaust manifold gasket again.
You can buy parts for your exhaust manifold gasket replacement from the following sources: 
  • The dealership/manufacturer: For OEM parts, made for your vehicle
  • Automotive parts shops or auto body retailers (AutoZone, NAPA Auto Parts, and Advance Auto Parts): For OEM or aftermarket parts
  • Online retailers (Amazon, RockAuto): For aftermarket parts

How will a mechanic replace my exhaust manifold gasket?

If your car is exhibiting signs of a damaged exhaust manifold gasket, your mechanic will run a diagnostic test to uncover the root issues. If your exhaust manifold gasket needs to be replaced, your mechanic will follow these steps:
  1. Preparation: With your vehicle hoisted, the mechanic will disconnect your car battery and let the engine cool down.
  2. Access the exhaust manifold: Depending on your vehicle, your mechanic will need to remove your engine’s cover, exhaust heat shields, coolant lines, air intake components, fuel or air filter, exhaust pipes, and parts of your air conditioning system.
  3. Disconnect the exhaust system: Your mechanic will remove the bolts that connect your exhaust pipe and exhaust manifold to disconnect the two parts. If the bolts are seized together, they may require an anti-seize compound for this part of the process.
  4. Remove the exhaust manifold: The mechanic will unbolt the exhaust manifold from the engine’s cylinder heads. Once the bolts are removed, the old exhaust manifold and old gasket may be removed from the engine.
  5. Cleaning: Your mechanic will inspect the cylinder head ports before attaching the new exhaust manifold gasket, and clean and repair them if necessary.
  6. Install the new exhaust manifold gasket: The mechanic will place the new gasket onto the cylinder heads in alignment with the exhaust ports. The exhaust manifold will then be placed on the gasket.
  7. Secure the exhaust manifold: Using the correct bolts, your mechanic will re-bolt the exhaust manifold to the cylinder heads.
  8. Reconnect the exhaust system: Your mechanic will seal the exhaust pipe to the exhaust manifold using the new exhaust manifold gasket.
  9. Replace components: Any engine or exhaust system components that were removed to access the exhaust manifold will be placed back in their original positions.
  10. Testing: Your mechanic will run a few tests to check for exhaust leaks or strange sounds. They may also take the vehicle for a test drive to ensure the engine and exhaust system are running efficiently.

What happens if I don’t replace my exhaust manifold gasket?

Have your vehicle inspected immediately if you notice any signs of a bad exhaust manifold gasket. A failing exhaust manifold gasket can lead to the following issues:
  • Harmful exhaust leaks
  • Decreased fuel economy 
  • Lower acceleration power 
  • Poor engine performance
  • Environmental pollution
  • Engine damage from high-temperature gas exposure

What is an exhaust manifold gasket?

The exhaust manifold gasket connects the exhaust manifold to the cylinder head surface, which prevents exhaust leaks in the system. The constant expansion and contraction of the components due to heat exposure can cause leaks over time.

When should I replace the exhaust manifold gasket on my car?

Look out for the following signs of a bad exhaust manifold gasket: 
  1. Exhaust leaks: You’ll notice a hissing or clicking sound from your engine compartment if your exhaust manifold is leaking due to a damaged gasket.
  2. Check engine light: Your car’s engine control unit (ECU) will pick up cues from your oxygen sensor if your exhaust manifold gasket is malfunctioning. As a result, you may notice your check engine light illuminating. 
  3. Exhaust fumes: If you notice a smell similar to burning plastic, your exhaust system may be leaking fumes due to a malfunctioning exhaust manifold gasket.
  4. Poor engine performance: Your engine will have a lower power output if your exhaust manifold gasket is damaged. 
  5. Lower fuel efficiency: A failing exhaust manifold gasket can lead to higher fuel consumption and lower fuel economy.
  6. Emissions test failure: Your vehicle will not pass an emissions test if your exhaust manifold gasket is damaged and causing exhaust leaks.
  7. Visible damage: If visually inspected, you may notice cracks or corrosion on your exhaust manifold gasket.
  8. High mileage: Your exhaust manifold gasket is prone to wear and tear over time. If your vehicle has a lot of miles on its odometer, you should have your exhaust system inspected just in case.

How often should an exhaust manifold gasket be replaced?

There aren’t precise replacement intervals for exhaust manifold gaskets, but they are subject to wear and tear from extreme heat exposure. Your best option is to routinely inspect your vehicle and engine to ensure your exhaust system, including the manifold gasket, are operating correctly.

Can I replace my exhaust manifold gasket myself?

The process to replace an exhaust manifold gasket is complex and involves a comprehensive understanding of car engines. To ensure the job is done correctly, you should take your vehicle to a certified mechanic.
