DESCRIPTION AND OPERATION
LUBRICATION SYSTEM
The pressurized system (Fig. 2) uses a rotary pump
(3) located in the front of the engine block, driven by
a gear which meshes directly with the crankshaft
gear. All the oil sent to every lubricated part is fil-
tered. The pump sends the oil through a pressure
relief valve (2) to the filter (7) and through galleries
in the crankcase to the crankshaft bearings (8), cam-
shaft bearings (11) and turbocharger (10). The piston
pins, connecting rod small ends and insides of the
pistons are lubricated and cooled by oil sprayed out
from jets (9) in the crankshaft mounting blocks. The
lubricating oil is sent to the rockers (12) through anexternal pipe (Fig. 3). A valve in the filter cartridge
enables the oil to be circulated even when the car-
tridge is clogged.

SERVICE PROCEDURES (Continued)

PISTON RINGÐREMOVAL
(1) Identification (ID) mark on face of upper and
intermediate piston rings must point toward piston
crown.
(2) Using a suitable ring expander, remove upper
and intermediate piston rings (Fig. 58).
(3) Remove the upper oil ring side rail, lower oil
ring side rail and then oil ring expander from piston.
(4) Carefully clean carbon from piston crowns,
skirts and ring grooves ensuring the 4 oil holes in
the oil control ring groove are clear.
FITTING PISTON RINGS
(1) Wipe cylinder bore clean. Insert ring and push
down with piston to ensure it is square in bore. The
ring gap measurement must be made with the ring
positioning at least 12 mm (0.50 in.) from bottom of
cylinder bore. Check gap with feeler gauge (Fig. 59).
Top compression ring gap .25 to .50 mm (.0098 to
.0196 in.). Second compression ring gap .25 to .35
mm (.0098 to .0137 in.). Oil control ring gap .25 to
.58 mm (.0098 to .0228 in.).
(2) If ring gaps exceed dimension given, new rings
or cylinder liners must be fitted. Keep piston rings in
piston sets.
(3) Check piston ring to groove clearance (Fig. 60).
Top compression ring gap .08 to .130 mm (.0031 to.0051 in.). Second compression ring gap .070 to .102
mm (.0027 to .0040 in.). Oil control ring gap .040 to
.072 mm (.0015 to .0028 in.).
PISTON RINGSÐINSTALLATION
(1) Install rings on the pistons using a suitable
ring expander (Fig. 58).
(2) Top compression ring is tapered and chromium
plated. The second ring is of the scraper type and
must be installed with scraping edge facing bottom of
the piston. The third is an oil control ring (Fig. 61).
Ring gaps must be positioned, before inserting piston
into the liners, as follows (Fig. 62).
(3) Top ring gap must be positioned at 30 degrees
to the right of the combustion chamber recess (look-
ing at the piston crown from above).
(4) Second piston ring gap should be positioned on
the opposite side of the combustion chamber recess.
(5) Oil control ring gap to be located 30 degrees to
the left of combustion chamber recess.

(3) If internal diameter of original bearing is being
checked and figures are not within specifications,
new bearings must be used.
(4) Check crankshaft main bearing journals to
bearing clearances. Clearances of main bearings is
.03 to .088mm (.0011 to .0035 in.).
OIL PAN
Remove all gasket material from cylinder block. Be
careful not gouge pan sealing surface.
CYLINDER LINER
INSPECTION
The cylinder walls should be checked for out-of-
round and taper with dail bore gauge. The cylinder
bore out-of-round is 0.100 mm (.0039 inch) maximum
and cylinder bore taper is 0.100 mm (0.0039 inch)
maximum. If the cylinder walls are badly scuffed or
scored, new liners should be installed and honed, and
new pistons and rings fitted.
Measure the cylinder bore at three levels in direc-
tions A and B (Fig. 79). Top measurement should be
10 mm (3/8 inch) down and bottom measurement
should be 10 mm ( 3/8 inch.) up from bottom of bore.

(9) Momentarily touch the other end of this
jumper wire to the negative terminal of the battery
for no more than 4 seconds.
(10) Place a rag or towel below the fuel line at the
quick connect to the rail.
(11) Disconnect the quick connect fitting to the
rail. Refer to Quick-Connect Fittings in this section.
(12) Return the fuel pump relay to the PDC.
(13) One or more Diagnostic Trouble Codes (DTC's)
may have been stored in the PCM memory due to the
fuel pump relay removal. The DRB scan tool must be
used to erase a DTC. Refer to group 25, On-Board
Diagnostics.
HOSES AND CLAMPS
Inspect all hose connections (clamps and quick con-
nect fittings) for completeness and leaks. Replace
cracked, scuffed, or swelled hoses. Replace hoses that
rub against other vehicle components or show sign of
wear.
Fuel injected vehicles use specially constructed
hoses. When replacing hoses, only use hoses marked
EFM/EFI.
When installing hoses, ensure that they are routed
away from contact with other vehicle components
that could rub against them and cause failure. Avoid
contact with clamps or other components that cause
abrasions or scuffing. Ensure that rubber hoses are
properly routed and avoid heat sources.
The hose clamps have rolled edges to prevent the
clamp from cutting into the hose. Only use clamps
that are original equipment or equivalent. Other
types of clamps may cut into the hoses and cause
high pressure fuel leaks. Tighten hose clamps to 1
N´m (10 in. lbs.) torque.
QUICK-CONNECT FITTINGS
REMOVAL
When disconnecting a quick-connect fitting, the
retainer will remain on the fuel tube nipple.
WARNING: RELEASE FUEL SYSTEM PRESSURE
BEFORE DISCONNECTING A QUICK-CONNECT FIT-
TINGS. REFER TO THE FUEL PRESSURE RELEASE
PROCEDURE.
(1) Disconnect negative cable from battery.
(2) Perform Fuel Pressure Release Procedure.
Refer to the Fuel Pressure Release Procedure in this
section.
(3) Squeeze retainer tabs together and pull fuel
tube/quick-connect fitting assembly off of fuel tube
nipple. The retainer will remain on fuel tube.
INSTALLATION
CAUTION: Never install a quick-connect fitting
without the retainer being either on the fuel tube or
already in the quick-connect fitting. In either case,
ensure the retainer locks securely into the quick-
connect fitting by firmly pulling on fuel tube and fit-
ting to ensure it is secured.
(1) Using a clean lint free cloth, clean the fuel tube
nipple and retainer.
(2) Prior to connecting the fitting to the fuel tube,
coat the fuel tube nipple with clean 30 weight engine
oil.
(3) Push the quick-connect fitting over the fuel
tube until theretainer seats and a click is heard.
(4) The plastic quick-connect fitting has windows
in the sides of the casing. When the fitting com-
pletely attaches to the fuel tube, the retainer locking
ears and the fuel tube shoulder are visible in the
windows. If they are not visible, the retainer was not
properly installed (Fig. 12).Do not rely upon the
audible click to confirm a secure connection.
CAUTION: When using the ASD Fuel System Test,
the Auto Shutdown (ASD) Relay remains energized
for either 7 minutes, until the test is stopped, or
until the ignition switch is turned to the Off posi-
tion.
(5) Use the DRB scan tool ASD Fuel System Test
to pressurize the fuel system. Check for leaks.

GENERAL INFORMATION
STEERING SYSTEM AND COMPONENT
DESCRIPTION
The power steering system consists of these four
major components. Power Steering Pump, Power
Steering Gear, Pressure Hose, and Return Line.
Turning of the steering wheel is converted into linear
travel through the meshing of the helical pinion
teeth with the rack teeth. Power assist steering is
provided by an open center, rotary type control valve.
It is used to direct oil from the pump to either side of
the integral steering rack piston.
Road feel is controlled by the diameter of a torsion
bar which initially steers the vehicle. As requiredsteering effort increases, as in a turn, the torsion bar
twists, causing relative rotary motion between the
rotary valve body and the valve spool. This move-
ment directs oil behind the integral rack piston,
which, in turn, builds up hydraulic pressure and
assists in the turning effort.
Drive tangs on the power steering gear pinion
shaft, mate loosely with the shaft of the steering
gear. This is to allow manual steering control to be
maintained, if the drive belt on the power steering
pump should break. However, under these conditions,
steering effort will significantly increase.
