Information:

Probable Causes
Oil Level
Excessive oil in the crankcaseOil Leaks
Oil leaks on the outside of the engine
Oil leaks in the combustion area of the cylindersOil Viscosity
Incorrect oil viscosityTurbocharger
Turbocharger sealRecommended Actions
Excessive Oil in the Crankcase
Check the engine oil level. Too much oil in the engine crankcase can cause the engine to consume oil. Remove excessive engine oil from the crankcase.Ensure that the dipstick is properly calibrated and/or that the dipstick is correct for the application. Calibrate the dipstick and/or replace the dipstick.Oil Leaks on the Outside of the Engine
Check for leakage at the seals at each end of the crankshaft. Look for leakage at the gasket for the engine oil pan and all lubrication system connections. Look for any engine oil that may be leaking from the crankcase breather. This can be caused by combustion gas leakage around the pistons. A dirty crankcase breather will cause high pressure in the crankcase. A dirty crankcase breather will cause the gaskets and the seals to leak.Oil Leaks in the Combustion Area of the Cylinder
Engine oil that is leaking into the combustion area of the cylinders can be the cause of blue smoke. There are several possible ways for engine oil to leak into the combustion area of the cylinders:
Leaks between worn valve guides and valve stems
Worn components or damaged components (pistons, piston rings, or dirty return holes for the engine oil)
Incorrect installation of the compression ring and/or the intermediate ring
Leaks past the seal rings in the turbocharger shaft
Overfilling of the crankcase
Wrong oil level gauge or guide tube
Sustained operation at light loadsOil Viscosity
Excessive consumption of engine oil can also result if engine oil with the wrong viscosity is used. Engine oil with a thin viscosity can be caused by fuel leakage into the crankcase or by increased engine temperature.Turbocharger Seal
Check for turbocharger shaft seal leakage. Remove the air inlet piping and the exhaust outlet piping from the turbocharger. Check the compressor wheel and the turbine for evidence of an oil leak. If necessary, repair the turbocharger or replace the turbocharger. Refer to Systems Operation/Testing and Adjusting, "Turbocharger Inspect".
