How to Diagnose

The followings are cautions to take in handling defects of turbo charger, which must be fully aware of;

Cautions When Examining the Defects:

1. After stopping the engine, check whether the bolts on pipe connecting section are loose as well as the connecting
condition of vacuum port and modulator, which is connected to the actuator.
2. During idling of the engine, check for leakage in the connecting section of pipe (hoses and pipes, duct connections,
after the turbo charger) by applying soap water. The leakage condition in the engine block and turbine housing
opening can be determined by the occurrence of abnormal noise of exhaust.
3. By running the engine at idle speed, abnormal vibration and noise can be checked. Immediately stop the engine
when abnormal vibration and noise is detected and make thorough inspection whether the turbo charger shaft
wheel has any damages as well as checking the condition of connections between pipes.
4. In case where the noise of engine is louder than usual, there is possibility of dampness in the areas related with air
cleaner and engine or engine block and turbo charger. And it could affect the smooth supply of engine oil and
discharge. 5. Check for damp condition in exhaust gas when there is sign of thermal discoloration or discharge of
carbon in connecting area of the duct.
6. When the engine rotates or in case where there is change in noise level, check for clogging of air cleaner or air
cleaner duct or if there is any significant amount of dust in the compressor housing.
7. During the inspection of center housing, inspect inside of the housing by removing the oil drain pipe to check for
sludge generation and its attachment condition at shaft area or turbine side.
8. Inspect or replace the air cleaner when the compressor wheel is damaged by inflow of foreign materials.
9. Inspect both side of the turbo charger wheel after removing inlet and outlet pipe of the turbo charger.
- Is the rotation smooth when the rotor is rotated by hand?
- Is the movement of bearing normal?
- Inspect whether there has been any signs of interference between two wheels.
Notice
It's important not to drive the engine when the intake manifold hose has been removed.
