While a severely damaged turbocharger *could* indirectly contribute to white smoke under specific circumstances (e.g., if it caused catastrophic engine damage leading to a cracked head or blown head gasket), the smoke would be a symptom of the *resulting* coolant leak, not the turbo failure itself.
A failing turbocharger is more likely to produce other symptoms like:
* Blue smoke: If the turbo seals fail, oil might leak into the combustion chamber, causing blue smoke.
* Reduced power: The engine will lose power as boost pressure is compromised.
* Whistling or whining noises: A failing turbocharger often makes distinctive sounds.
* Oil leaks: Oil leaks might appear around the turbocharger itself.
Therefore, while a connection is remotely possible through consequential damage, white smoke is not a typical symptom of turbocharger failure in a diesel engine. The cause of the white smoke should be investigated separately.
