INSPECTION
TURBOCHARGER ASSEMBLY CHECK . .
1. Visually check the turbine wheel and
wheel for cracking or other damage.
2. Check whether the turbine wheel and
compressor
wheel can be easily turned by
3. Check for oil leakage from the turbocharger asse mbly.
4.Check if the turbocharger waste gate valve remains open.
If any problem is found, replace the part
.
OIL PIPE ASSEMBLY AND OIL-RETURN PIPE
Check the oil pipe assembly and oil-return pipe for clogging,
bending, or other damage. If there is clogging, clea n it.
