Before you begin inspection of the turbocharger, be sure that the inlet air restriction is within the specifications for your engine. Be sure that the exhaust system restriction is within the specifications for your engine. Refer to Testing and Adjusting, "Air Inlet and Exhaust System - Inspect".The condition of the turbocharger will have definite effects on engine performance. Use the following inspections and procedures to determine the condition of the turbocharger.
Inspection of the compressor wheel and the compressor housing
Inspection of the turbine wheel and the turbine housing
Inspection of the wastegateInspection of the Compressor Wheel and the Compressor Housing

Remove the air cleaner from the compressor inlet.
Inspect compressor wheel for damage from a foreign object. If there is damage, determine the source of the foreign object. As required, clean the inlet system and repair the intake system. Replace the turbocharger. If there is no damage, go to Step 4.
Turn the rotating assembly by hand. While you turn the assembly, push the assembly sideways. The assembly should turn freely. Compressor wheel (2) should not rub compressor housing (1) . The turbocharger must be replaced if the compressor wheel rubs the compressor housing. If there is no rubbing or scraping, go to Step 4.
Inspect compressor wheel (2) and compressor housing (1) for oil leakage. An oil leak from the compressor wheel may deposit oil in the aftercooler (if equipped). Drain and clean the aftercooler if you find oil in the aftercooler.
Check the oil level in the crankcase. If the oil level is too high, adjust the oil level.
Inspect the air cleaner element for restriction. If restriction is found, correct the problem.
Inspect the engine crankcase breather. Clean the breather or replace the breather if the breather is plugged.
Remove the oil drain tube. Inspect the oil drain hole and the oil drain tube for oil sludge. Inspect the area between the bearings of the rotating assembly shaft. If necessary, clean the rotating assembly shaft, the oil drain hole, and the oil drain tube.
If Steps 4.a through 4.d did not reveal the source of the oil leakage, the turbocharger has internal damage. Replace the turbocharger.Inspection of the Turbine Wheel and the Turbine Housing
