Checking Turbine Housing Inlet Ports
Turbine Housing Inlet
Check the turbine housing inlet ports (arrow) for oil in
housing, excessive carbon deposit or erosion of center
walls.
NOTE: If the inlet is wet with oil, or has excessive carbon
deposits, an engine problem is likely. Center wall
erosion (cracking or missing pieces), indicates
excessive exhaust temperature.
