A faulty turbo can cause low
power, black smoke, excessive oil consumption, oil in the intake,
oil in the exhaust as well as other problems. To determine if
the turbo is the problem an inspection of the shaft assembly can
be made. Remove the intake and/or exhaust plumbing to the turbo.
Look for any evidence that the wheel has toughed or rubbed the
housing. If no signs are evident physically push the wheel to
one side and see if the wheel can be made to contact the housing.
If either of these conditions exist the turbo should be repaired
or replaced. If the shaft is tight and wheels have not rubbed
other checks should be made before replacing the turbo.
