Trouble diagnosis of turbocharger
Preliminary check:
Check that the VNT control valve system has no malfunction. Refer
to EC section, ªECM Terminals and Reference Valueº in ªTROUBLE
DIAGNOSIS Ð GENERAL DESCRIPTIONº.
ICheck that the engine oil level is between MIN and MAX of the
dipstick. (When the engine oil amount is more than MAX, the
oil flows into the inlet duct through the blow-by gas passage,
and the turbocharger is misjudged failure.)
IAsk the customer if he/she always runs the vehicle in idle
engine speed to cool the oil down after driving.
IReplace the turbocharger assembly when any malfunction is
found after unit inspections specified in the table below.
IIf no malfunction is found after the unit inspections, judge that
the turbocharger body has no failure. Check the other parts
again.

INSTALLATION
1. Install catalyst.
:29-39N×m (2.9 - 3.3 kg-m, 21 - 23 ft-lb)
Place the protruding area of the gasket between the turbocharger
and the exhaust outlet upwards, and install the lipped side to the
turbocharger side. Refer to the figure, EM-14.
2. Install in the reverse order of removal.

VALVE GUIDE CLEARANCE
IValve guide clearance should be measured parallel with
rocker arm. (Generally, a large amount of wear occurs in
this direction.)

VALVE GUIDE REPLACEMENT
1. Heat cylinder head 150 to 160ÉC (302 to 320ÉF) in oil.
2. Drive out valve guide with a hammer and suitable tool.
