1. Loud Whining or Whistling Noise: A turbocharger that's in good condition should make a quiet whooshing sound. If you start to hear a loud whining or whistling noise, it could be a sign of a faulty turbo.
2. Excessive Engine Smoke: A turbocharger can cause excessive smoke if its seals are failing or if there's a problem with the oil supply. If you notice blue or black smoke coming from your exhaust, it could be a sign of a turbo issue.
3. Lack of Power or Boost: A turbocharger helps increase engine power by compressing air and forcing it into the engine. If you notice a sudden loss of power or boost, it could be due to a faulty turbo.
4. Check Engine Light: If your check engine light comes on and you're experiencing any of the above symptoms, it could be a sign of a turbocharger issue.
5. Oil Leakage: A faulty turbocharger can cause oil to leak. Check the area around your turbo for oil residue or drips.
6. Physical Damage: If your turbocharger has sustained physical damage, such as a cracked housing or broken blades, it will need to be replaced.
