Turbos force more air into the cylinder, which can be mixed with more fuel to create more power. Turbos use the energy of the engine’s exhaust gases to compress air into the engine
There are several ways that your vehicle will let you know that its turbo is in need of maintenance or repairs:
- Check engine warning lights
- Power loss - If you notice that your turbocharged vehicle is accelerating more slowly than usual, or isn’t capable of reaching the speeds it once could, this may be a sign that your turbo is failing.
- A smoking exhaust - If the turbo housing has cracked, or the internal seals have blown, oil will start to leak into your exhaust system. As this burns off, it produces a distinctive blue/grey smoke.
- A loud whining noise - Often, a failing turbocharger will make a loud, distinctive noise when under boost if compressor wheel damaged.
