Exhaust Manifold and Turbocharger Inspection

INSPECTION

EXHAUST MANIFOLD CHECK

1. Check the exhaust manifold for damage and cracks, and replace it if necessary.

2. Using a straight edge and a thickness gauge, check for distortion of the cylinder head and turbocharger installation surface. If it exceeds the limit value, replace it.

Limit[ Cylinder head assembly side]: 0.70 mm (0.028 inch)
Limit[ Turbocharger assembly side]: 0.40 mm (0.016 inch)


TURBOCHARGER ASSEMBLY CHECK

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 whether or not the turbocharger waste gate regulating valve remains open. If any problem is found, replace the part after disassembly.
