PINPOINT TEST A : BLUE SMOKE WITH EXCESSIVE TURBOCHARGER NOISE |
TEST CONDITIONS | DETAILS/RESULTS/ACTIONS |
A1: INSPECT THE TURBOCHARGER ROTOR VANES FOR DAMAGE |
| CAUTION:Make sure that the inside of the pipe ends are clean and free of oil residue. 1 Remove the turbocharger intake pipe. |
| 2 Inspect the turbocharger rotor vanes for damage. |
| Is there visible damage to the rotor vanes? Yes No |
A2: CHECK FOR FOREIGN MATERIAL IN THE INTAKE AIR SYSTEM COMPONENTS |
| 1 Check the intake air system components for signs of foreign material. |
| Are there any signs of foreign material? Yes CLEAN the intake air system components. INSTALL a new turbocharger. REFER to: Turbocharger - 110 PS, Vehicles With: Fixed Vane Turbocharger (303-04C, Removal and Installation). TEST the system for normal operation. No |
A3: CHECK THE TURBOCHARGER BEARINGS FOR EXCESSIVE MOVEMENT |
NOTE:A small amount of movement in the bearings is normal. |
NOTE:The initial rotor rotation of a cold turbocharger may feel rough and uneven but should rotate freely after a few turns. |
| 1 Make sure that the turbocharger rotor spins freely within the housing. - 1. With the turbocharger stationary, gently lift the shaft (the shaft will naturally lay in the bottom of the bearings).
- 2. Make sure that the rotor spins freely within the housing.
|
| Does the rotor spin freely within the housing? Yes No INSTALL a new turbocharger. REFER to: Turbocharger - 110 PS, Vehicles With: Fixed Vane Turbocharger (303-04C, Removal and Installation). TEST the system for normal operation. |
A4: CHECK THE TURBOCHARGER OIL SUPPLY TUBE FOR BLOCKAGE |
| 1 Remove the turbocharger oil supply tube. |
| 2 Using workshop compressed air and a compressed air nozzle, check the oil supply tube for blockage. |
| Is there any signs of blockage? Yes No INSTALL a new turbocharger and turbocharger oil supply tube. REFER to: Turbocharger - 110 PS, Vehicles With: Fixed Vane Turbocharger (303-04C, Removal and Installation). TEST the system for normal operation. |
A5: CHECK THE TURBOCHARGER OIL SUPPLY TUBE OIL GALLERY FOR BLOCKAGE |
| 1 Visually inspect the oil supply tube oil gallery in the cylinder block for blockage. |
| Is the oil supply tube oil gallery free from blockage? Yes INSTALL a new turbocharger and turbocharger oil supply tube. REFER to: Turbocharger - 110 PS, Vehicles With: Fixed Vane Turbocharger (303-04C, Removal and Installation). TEST the system for normal operation. No REMOVE the blockage. INSTALL a new turbocharger. REFER to: Turbocharger - 110 PS, Vehicles With: Fixed Vane Turbocharger (303-04C, Removal and Installation). TEST the system for normal operation. |
