Excessive Oil Consumption or White Exhaust
POSSIBLE CAUSE: FAULTY TURBOCHARGER SEALTESTING PROCEDURE:
(A) Check for oil leakage in exhaust system.
- Remove the turbine elbow from the turbocharger and check for excessive carbon deposits on the turbine wheel. Excessive carbon deposits indicate a faulty turbocharger.
(B) Check for oil leakage in intake air system.
- Check for axial and radial play of turbine shaft and replace the turbocharger if necessary. "Refer to Turbine Shaft Inspection".
Maximum axial play: 0.110 mm (0.0045 in.)
Maximum radial play: 0.162 mm (0.0064 in.)
NOTICE: Some oil mist in the blowby from the PCV is normal. Do not mistake it for an oil leak from the turbocharger.
