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.

DS

DS is the premium automobile marque of the Groupe PSA. First announced in 2009 by Citroën as its premium sub-brand; it was suggested to be an abbreviation of different spirit or distinctive series. However, in French, the name is considered a play on words, as the translation of déesse becomes goddess in English.

How popular is DS in the United Kingdom?

As a newcomer to the UK market in its own right, there were around 35k DS cars on the roads in the UK by the end of 2018. Whether those figures will continue to rise at the same rate shown since their introduction in 2015, only time will tell.

Looking to provide a standalone marque to initially compete with brands such as Volkswagen and Audi, PSA decided that neither Citroën nor Peugeot would be able to carry the brand strength that would be able to make a serious threat in the market with an elevated price-point at the level of quality and luxury they set out to achieve.

DS: Establishing a new range of upmarket models

To compete with the likes of Audi, BMW and Mercedes-Benz, DS introduced a range of hatchbacks, saloons and SUVs but it’s undoubtedly their supermini city car that is proving the most popular.

The DS3, sold as a 3-door hatchback or a convertible, is available in countless customisation options and also as the subcompact luxury crossover SUV DS3 Crossback. The DS3 was voted Car of the Year by Top Gear Magazine, and first place supermini four times in a row in the JD Power Satisfaction UK Survey.

DS: Don’t be fooled into thinking they’re just a one trick pony

At the other end of the range you’ll find the DS7 Crossback. Here’s a large SUV designed to compete directly with the Audi Q5, the BMW X3 and the Mercedes-Benz GLC; that’s quite a jump for a car that’s built by Citroën.

The models that you’ll find between the DS3 and the DS7 are created with the same style for the market in mind. The DS4, a mixture of hatchback and SUV, and the DS5, a bigger hatchback priced and pitched against the Audi A4, the BMW 3 Series and the Mercedes C-Class saloons.

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.
