Exhaust Manifold Gasket Replacement

What is an Exhaust Manifold Gasket

You don't want your engine's exhaust pouring into your car. The exhaust manifold connects to your exhaust pipe, carrying gases towards the muffler until they exit via the tailpipe. It is the main gasket that seals and pressurises the entire exhaust system. Gaskets are used to seal gaps between two different surfaces. The surface where the exhaust manifold meets the engines parts must be sealed - this is what the Exhaust Manifold Gasket does. 

Why do you need an Exhaust Manifold Gasket

You don't want your stinky exhaust leaking into your vehicle. Or even worse in your engine bay! The exhaust manifold gasket prevents the exhaust leaking into these precious parts of your car.  

How to tell if you need a new Exhaust Manifold Gasket

The Exhaust Manifold Gasket can have a few symptoms which means it needs a replacement. Your engine could be extra noisy, you may experience a decrease in power, acceleration or fuel efficiency. The most important and common symptom is if you can detect a burning burning smell from the engine bay. 

How is an Exhaust Manifold Gasket replaced

You will need a professional mechanic to replace your exhaust manifold gasket. They will disassemble the engine bay to expose the exhaust manifold. The exhaust pipe will then be disconnected from the exhaust manifold. The old gasket will be unbolted and removed. Your mechanic will make sure all the components are in great shape before installing the new gasket. 

How much does Exhaust Manifold Gasket cost

A new engine gasket usually starts around $500 and can be over $800 depending on your car. 

How often do I need an Exhaust Manifold Gasket replaced

You would be unlucky to need a new manifold gasket replacement before 100,000km unless there are manufacturing flaws or various running problems. The main concern is your manifold gasket burning out.  

Is a broken Exhaust Manifold Gasket unsafe
