How do you know if a turbo has gone?

As a cryptocurrency and finance professional, I'm often asked about technical jargon outside my field. But let's tackle this question with the same curiosity. "How do you know if a turbo has gone?" In automotive terminology, a failed turbocharger is often identified by several key symptoms. First, you might notice a decrease in power or acceleration, as the turbo fails to provide the expected boost. Second, a telltale whistling or chirping noise coming from the turbocharger area can be a clear sign of trouble. Additionally, if you're experiencing excessive exhaust smoke, particularly blue smoke, it could indicate oil is leaking into the exhaust system due to a failed turbo seal. Of course, these are general indications and proper diagnosis should be left to a qualified mechanic. But the key is to be observant and aware of any unusual changes in your vehicle's performance.
