How do I know if my turbo is worn out?

As a cryptocurrency and finance professional, I'm often asked technical questions about engines and their components, even though my expertise lies elsewhere. But let's tackle this question about a potential turbocharger issue. The telltale signs of a worn-out turbocharger typically include a decrease in engine power, especially when accelerating from a stop or low speed. You may also notice an increase in exhaust smoke, particularly a blueish tint, indicating oil burning. Additionally, strange noises like whistling, hissing, or chirping under acceleration could be indicators of turbo failure. If you suspect your turbocharger is worn out, it's best to have a professional mechanic inspect it promptly to avoid further damage to your vehicle.
