Visual Inspection

1. Visually check the turbine wheel and the compressor wheel for cracking or other damage.
2. Check whether the turbine wheel and the compressor wheel can be easily turned by hand.
3. Check for oil leakage from the turbocharger assembly.
4. Check if the turbocharger waste gate valve remains open. If any problem is found, replace the part after disassembly.
5. Check the oil pipe assembly and oil-return pipe for clogging, bending, or other damage. If there is clogging, clean it.
