Exhaust 0.30 to 0.40 mm (0.0118 to 0.0157 in.)
(b) Turn the crankshaft clockwise 1 revolution (360
) and set
No. 4 cylinder to TDC/compression.
(c) Check only the valve indicated in the illustration. (1) Using a feeler gauge, measure the clearance be-tween the valve lifter and camshaft.
(2) Record the out±of specification valve clearance measurements. They will be used later to determine
the required replacement adjusting shim.
Valve clearance (Cold):

19.INSTALL FUEL INLET PIPE SUB±ASSY
NOTICE:

In case of having the common rail replaced, must re-
place fuel inlet pipe, too.

When assembling the pipe, perform the operation
with the engine cold under room temperature.
(a)Temporarily install the fuel inlet pipe.
(b)Using SST, tighten the nut of the fuel inlet pipe to the com-
mon rail side.

PRECAUTION
1.PRECAUTION
(a)Before working on fuel system, disconnect negative (±) battery cable.
(b)Do not smoke or work near fire when handling the fuel system.
(c)Keep gasoline away from rubber or leather parts.
2.DISCHARGE FUEL SYSTEM PRESSURE
CAUTION:

Do not disconnect any part of the fuel system until
you have discharged the fuel system pressure.

Even after discharging the fuel pressure, place a
shop rag over fittings as you separate them to reduce
risk of fuel spray on yourself or in the engine compart-
ment.
(a)Disconnect the fuel pump connector.
(b)Start the engine. After the engine has stopped, turn the ignition switch OFF.
(c)Disconnect the negative (±) battery cable.
(d)Connect the fuel pump connector.
3.FUEL SYSTEM
(a)When disconnecting the high fuel pressure line, a large amount of gasoline will spill out, so observe these proce-
dures.
(1)Discharge the pressure in the fuel system. (See step 2)
(2)Disconnect the fuel pump tube. (See page 11±93)
(3) Drain the fuel that remained inside the fuel pump
tube.
(4) Cover the disconnected fuel pump tubes with a vinyl or a plastic bag to prevent damage and dirt.
(5) Place a tray under the vehicle or point of disconnec- tion to catch any fuel that may spill.
