During an exhaust manifold gasket replacement, a mechanic will remove your defective gasket, apply anti-seize, and install a new functioning gasket. This helps prevent hot exhaust gases from leaking out of the car’s engine.
A malfunctioning exhaust manifold gasket is actually a fire risk. Replacing this crucial car part can run you anywhere from $150 to $500 depending on the make, model, and year of your car.
Jerry, the car insurance super app, is breaking down everything you need to know about replacing your exhaust manifold gasket.
The exact cost varies between different Bentley models. For example, newer vehicle models are usually made with more expensive materials, so recent or high-end models will cost more, especially if your service requires a part replacement. Use the table below to estimate the cost for your own vehicle.

What is an exhaust manifold repair?

In this service, a mechanic will determine if your exhaust manifold is faulty and replace it with a properly working one if so.
The exhaust manifold can be a series of pipes or a cast iron manifold assembly, depending on your engine and vehicle type. The exhaust manifold collects the burned exhaust gases from the engine cylinders and ejects them via the tailpipe.
This part can leak over time due to normal wear and tear.

How to repair your exhaust manifold

To repair an exhaust manifold, the mechanic will usually complete the following steps:
  • Check for cracks or breaks in the manifold
  • Remove the faulty exhaust manifold
  • Examine the exhaust studs, cleaning carbon and old gasket from the cylinder head
  • Replace the exhaust manifold and gasket
  • Restart the engine and look for any leaks in the exhaust system
It’s possible that a broken mounting bolt has caused your exhaust manifold to leak. Removing this may cost you extra to compensate for the mechanic’s extra labor.

How do I know if I need to get my exhaust manifold repaired?

There are a few signs that your exhaust manifold may need to be repaired:
  • Your engine is making loud noises
  • Your engine isn’t performing well
  • The check engine light is illuminated
  • Smells are emanating from the engine compartment (such as the smell of melting plastic)

How important is repairing my exhaust manifold?

A leaking exhaust manifold is a health and safety hazard. Melting plastic components from neighboring engine compartments can damage nearby parts and become a fire hazard.
A leaky exhaust manifold can also negatively impact overall engine performance.
