Can the turbo cause white smoke?

Yes, a turbocharger can cause white smoke if it is failing. If the seals within the turbo are compromised, engine oil can leak into the exhaust system, resulting in white smoke due to the burning oil. Additionally, a coolant leak into the combustion chamber can also produce white smoke, which may indicate other issues like a blown head gasket. It's essential to diagnose the exact cause to prevent further engine damage.
