PURPOSE: A turbo charger protecting apparatus for a vehicle engine is provided to prevent a bearing part of a turbo charger from being damaged by supplying engine oil to the turbo charger. CONSTITUTION: A turbo charger protecting apparatus includes an oil pump(100) for supplying oil to an engine. One end of a turbo charger(200) is connected to an intake manifold and the other end of the turbo charger(200) is connected to an exhaust manifold so as to rotate turbine by using pressure of exhaust gas. The turbo charger(200) supplies intake air to the engine by compressing intake air. Oil discharged from the turbo charger(200) is received in an oil pan(300). An accumulator(400) is provided to constantly maintain pressure of oil supplied from the oil pump(100). A pressure regulator(500) is varied depending on pressure of the accumulator(400). First and second check valves(600,700) are provided to prevent oil, which is discharged from the accumulator(400), from penetrating into the oil pump. A solenoid valve(800) supplies oil having predetermined pressure to the turbo charger(200).
