Rework Procedure

Clean the oil tracks from the inlet surface.

Examine the 1180398 Turbocharger for rubbing between the compressor wheel and housing.

If there is no sign of rubbing, reinstall the housing on the turbocharger.

On replaced turbochargers, carefully reinstall the compressor housing and return the turbocharger as a Warranty Core.
