What does an intake manifold gasket do?

Gaskets are the seals placed between engine components to prevent any leaks. The intake manifold gasket is located between the engine and the air intake manifold and seals the two components.

It is usually made of a hard metal or composite material and ensures the air flows from the air inlets into the intake manifold and eventually reaches the engine where it helps to burn the fuel inside the engine cylinder. The intake manifold also serves as a device for cooling the engine coolant which passes through it.

Mini

Mini is a British automotive marque that has been owned by the German multinational vehicle manufacturer BMW since 2000.

The Mini brand was originally introduced in 1969 when the vehicle model became a marque in its own right, breaking away from the Austin and Morris brands under the British Leyland umbrella.

How popular is Mini in the United Kingdom?

The Mini Hatch was the 7th best selling car of 2018 in the UK. Mini is a consistent favourite among buyers with a leaning for British cultural icons and retro styling.

There are around 750k Mini cars on the roads, showing that the brand is still as popular as ever due to their compact sizing, attractive styling and its reputation as a classy and classic small car.

Mini: a premium product of British motoring

With its unique and unmistakable styling, Mini is firmly placed as a premium product. Its ownership by BMW has added advantages in production, by being able to lean on the executive luxury German marque for many of the advanced technological systems and specialist industry knowledge used in their manufacture.

A piece of British culture and a Hollywood star

Enhancing its popularity as a household name, the original British Mini became a star of the silver screen when it appeared predominantly in the gold-heist movie ‘The Italian Job’ in 1969, starring Michael Caine and Noel Coward. With a remake hitting the screens in 2003, the new Mini was called on to star once again, and a selection of Mini hatch models continued the tradition by featuring in the film.

Mini: a new competitor to the most popular 3-door hatchbacks

Despite its small footprint, the Mini hatch is providing real competition to the Audi A1 and VW Polo due to its premium quality build. And with the weight of BMW behind them, it’s easy to see why.

How often should an intake manifold gasket need replacing?

The intake manifold gasket on a car should typically last around 50,000 to 75,000 miles. However, this varies between cars and between drivers. In some instances, the gasket will fail prematurely due to the heat and pressures it’s exposed to on a daily basis. Some may last a lot longer in a less used or newer car.

And remember, failing to have your car maintained and repaired if you think there may be a problem with your intake manifold gasket could result in more costly and serious damage to your engine. A bad gasket will also impact your car’s power and fuel economy, making it more expensive to run.

The law, vehicle regulations and your MOT

There are strict regulations regarding exhaust systems and car emissions in the UK. A car's exhaust system, including the manifold and gaskets, cannot have any serious leaks, corrosion or cracks. An annual MOT tests both the exhaust system for leaks and deterioration and the emissions coming from the exhaust system.

What causes an intake manifold gasket to break?

During the combustion process the engine cools and heats continuously. The intake manifold gasket is constantly exposed to these extreme temperature fluctuations inside the engine, making it especially prone to wear and cracking.

When should an intake manifold gasket be replaced?

It is important to make sure that the intake manifold gasket is always in good condition as a damaged gasket can lead to engine coolant leaks and an overheating engine. We therefore advise that you replace a bad gasket as soon as you notice any of the symptoms below. The sooner you deal with the issue, the less likely it is that you’ll have to fork out for larger, costly repairs in the future.

What are the signs of a bad intake manifold gasket?

Usually, there a few signs you can look for:

• If the ‘check engine’ warning light illuminates.

• Engine misfire.

• Loss of engine power.

• Poor fuel efficiency.

• When the engine is running at a higher temperature or overheating more than usual.

• When there is fluid under the car, coming from the engine.

• When coolant is visible around the intake manifold.

• When the engine does not run as smoothly as usual.

What happens during an intake manifold gasket replacement?

During the repair our certified mechanics will:

• Inspect the intake manifold and gasket for leaks.

• Read the car's ECU to find any fault codes.

• Clean the air intake ports of the engine of dirt buildup.

• If necessary, they will replace the intake manifold gasket.

• Advise if other related parts need to be replaced.

• Finally they will test drive the car.

What is the average life of an intake manifold gasket?

The intake manifold gasket on a car should typically last around 50,000 to 75,000 miles. However, this varies between cars and between drivers. In some instances, the gasket will fail prematurely due to the heat and pressures it’s exposed to on a daily basis. Some may last a lot longer in a less used or newer car.

Can you drive with a broken intake manifold gasket?

We wouldn’t recommend driving if you suspect you have a bad or leaky intake manifold gasket. A bad leak will wreak havoc on your engine as it will disrupt the air fuel mixture in your engine. This could cause your car to overheat, stall frequently, misfire, run rough, or worst case your engine could seize, which will result in a costly, but avoidable, repair.

What happens if you don't change a bad intake manifold gasket?

Failing to have your car maintained and repaired if you think there may be a problem with your intake manifold gasket could result in more costly and serious damage to your engine. A bad gasket will also impact your car’s power and fuel economy, making it more expensive to run.

Do intake manifold gaskets deteriorate with age?

The intake manifold gasket on a car should typically last around 50,000 to 75,000 miles. However they can experience premature wear and tear as they are constantly exposed to extreme temperature fluctuations during your car’s combustion cycle.
