If a pool of oil (not wall wetting) is found in the turbocharger compressor inlet or air inlet connection of the turbocharger, check the system for high air intake restriction. Refer to Inspection .
If a pool of oil is found on the compressor outlet connection and there is not a pool of oil on the intake side, remove and replace the entire turbocharger assembly.
