Which outcome occurs when an engine's turbocharger experiences oil oxidation due to excessive heat?

💡 Explanation

When turbocharger oil oxidizes, thermal breakdown causes sludge and varnish formation, diminishing its lubricating qualities, leading to increased friction and wear on the turbocharger bearings. Therefore bearing failure from reduced lubrication results, rather than stall, malfunction, or cracking, which stem from different underlying issues.
