What are the symptoms of a damaged turbo in the Great Wall C50?

[VonCamila]

Here are the symptoms of a damaged turbo in the Great Wall C50: 1. Poor sealing of the turbocharger impeller shaft: Blue smoke from the exhaust at idle, varying in intensity. No blue smoke while driving, but engine oil consumption occurs. 2. Severe blockage of the exhaust gas recirculation pipe: Blue smoke from the exhaust at idle and while driving, worsening when accelerating, with significant engine oil consumption. 3. Wear or aging of piston rings, cylinder walls, or valve oil seals: Heavy blue smoke from the vehicle, abnormal noise from the turbocharger turbine end, and oil leakage from the turbocharger turbine end. 4. Turbocharger air duct rupture: A 'fluttering' abnormal noise when accelerating or decelerating.
