A turbocharger, also known as a turbo, is an additional system used by automakers to boost engine power that provides the same level of power on smaller cars as it does on larger cars. A bad turbo affects the performance of the car, requiring timely repairs. Let's find out what bad turbo symptoms are:


In practice, a turbocharger is effectively two small air fans that sit on the same metal shaft so that they both spin together. One of these fans, known as a turbine, sits in the exhaust gas flow of the cylinders. As the cylinders blow hot gas past the
fan blades, they rotate and the shaft to which they are connected also rotates. Now the second fan, known as the compressor, also rotates on the same shaft as the turbine. It is mounted in the car's air intake, so when it turns it draws air into the car and pushes it into the cylinders.

So this is how the turbo works in theory and in practice. Now that you understand the principles of operation, let's move on to the bad turbo symptoms.

1.
Slow acceleration

As the main function of the turbo, it helps the smaller cars have more power than the larger ones, which means it is more powerful. One of the first noticeable symptoms is a lack of strength and slow acceleration. If you find that it is not accelerating as fast as it used to, the first thing to do is check the turbo. Similarly, a turbo-charged car that has difficulty maintaining high speeds or is unable to reach speeds at which it might once be can experience a turbo failure. Hence, one of the bad turbo symptoms to watch out for is loss of power.

2.
Whining engine

The turbo actually makes the engine quieter because it muffles the noise of the air intake. Then, if you hear a noise from the engine that is louder than usual, which is a bit like a police siren, the chances are you've been causing turbo symptoms to be 100%.

If you ignore the blown turbo sound, the noise will get louder and louder and your vehicle condition will deteriorate. If you notice your engine whining, consider getting a professional mechanic to take a look at your car.


3.
Burning engine oil

One of the bad turbo symptoms is that the car is burning excessive oil than usual. You can look into the turbine with an endoscope. If there is oil inside it is a sign of turbo failure symptoms. You should fix the problem ASAP as the turbo will go untreated and your turbo will eventually fail.


4.
Excessive exhaust smoke

If you see your car's blue or gray smoke while driving, the percentage that your car has a bad turbo is very high. So why gray smoke? A crack in the turbo case or damaged inner seals can lead to an oil leak in the exhaust system, which results in gray or blue air.

Otherwise, you can feel the discolored fumes when the engine speed increases shortly after idling. Don't ignore this symptom and take your car to the mechanic right after that to fix it as soon as possible.

5.
Check the engine light

On most modern cars, computer diagnostics will detect a faulty turbo, which will lead to "checking your engine". It's a sign that the car is trying to tell you that something bad has happened to your turbo.

If so, you may need a professional who can help you pinpoint the exact vehicle problem. Hence, taking your car to the mechanic is a good solution.

6.
The boost pressure gauge

The boost gauge is usually seen on some car models. So if your car is equipped with the boost gauge, there is an excellent way to find out how good our turbo is. That way, you can diagnose your car problem even if you can't clearly see the bad turbo symptoms.

You may notice a drop in boost pressure. This is a sign that your turbocharger is performing poorly. A drop can be due to various turbo failures. You should therefore have your turbocharger checked by a specialist as soon as possible.


Conclusion

There are many reasons for a blown turbo and there are also many bad turbo symptoms such as exhaust smoke, gray smoke, engine noise, boost gauge, burnt oil. Make sure you take your car to the garage for maintenance frequently. In addition, every time you perform maintenance, your oil will be changed to prevent carbon build-up. In the event that the turbo is too old, it's a good idea to replace a new one.

Ensure you get to the root cause why the turbo failed in the first place. Do not replace the turbo in a hurry, otherwise, it will fail again.

Well done op
