2. AUTO TENSIONER CHECK
(1) Stop the engine from the idle speed and check that the
belt rests within the auto tensioner pulley width.
(2) Remove the drive belt.
(For the removal of the drive belt, refer to P.11-9.)
(3) Fit a spinner handle or similar tool into the tool mounting
hole of the auto tensioner and turn the tensioner clockwise and counterclockwise to ensure that it does not bind.
(4) If step (1) or (3), or both, have been checked abnormally,
replace the auto tensioner.
(5) Reinstall the drive belt.
3. LASH ADJUSTER CHECK
NOTE If an unusual knocking noise can be heard immediately after the engine has started or while it is running and if that is probably attributable to the lash adjuster, make the following checks.
(1) Check the engine oil and add or change oil as necessary.
NOTE (1) If the engine oil level is low, air is taken in through
the oil screen, entering the oil passage.
(2) If the oil level is too high, the cranks agitate oil causing
oil to trap a large amount of air.
(3) Air does not easily separate from a deteriorated oil
that can contain an increased amount of air.
When air trapped in oil for these reasons gets into the high-pressure chamber of the lash adjuster, the air in the high-pressure chamber is compressed to shrink the lash adjuster excessively while the valve is opening, resulting in an unusual noise occurring. This is the same symptom developing when the valve clearance is adjusted to an excessive value. The problem in this case is gone when air is released from the lash adjuster.
(2) Start the engine and carry out several cycles (10 or less)
of mild racing*. If the noise is gone after racing, it indicates that air has been released from the high-pressure chamber of the lash adjuster, restoring the lash adjuster to normal operating conditions. *: Gradually (extending over a 30-sec. period) increase
the engine speed from idle speed to 3,000 r/min and then reduce it down to the idle speed gradually (extending over a 30-sec. period).
11-5
NOTE (1) If the vehicle is parked on a slope for a long time,
the amount of oil in the lash adjuster will decrease, causing air to get into the high-pressure chamber when the engine is started.
(2) After the vehicle has been parked for a long time,
oil drains out of the oil passage and it takes a long time for the oil to reach the lash adjuster. This can cause air to get into the high-pressure chamber.

(3) If the noise is not eliminated by racing, follow these steps
to check the lash adjuster. a. Stop the engine. b. Bring no. 1 cylinder to TDC on the compression stroke. c. Push the rocker arms indicated by arrow A on the
left to see if they go down. d. Slowly turn the crankshaft clockwise 360_. e. Perform the same step as step c for rocker arms
indicated by arrow B.
f. Push the part of the rocker arm which contacts the
top of the lash adjuster. If the rocker arm can be
easily moved down to the bottom, the lash adjuster
is defective, requiring replacement.
When the lash adjuster is replaced, be sure first to
bleed the lash adjuster of air before installation. Then,
perform steps a through e to ensure that no abnormal
symptoms are noted.
NOTE
(1) The leak-down test is an effective means to
accurately determine if the lash adjuster is operational or not.
(2) For the leak-down test and bleeding procedures,
refer to ENGINE WORKSHOP MANUAL. If the rocker arm is felt binding and cannot be pushed downward as you push it, the lash adjuster is operational. Check for other possible causes for the noise.
MD998782

(4) Lash adjuster replacement
Caution From the cylinder from which the lash adjuster is to be removed, turn the crankshaft to lower the piston, as the valve contacts the piston when pushed down. A rocker arm cannot be removed if it is lifted by the cam. If this is the case, turn the crankshaft so that the arm is not lifted.
a. Using the special tool, push the valve downward to
remove the roller rocker arm. b. Remove the lash adjuster from the cylinder head. c. Mount a brandnew lash adjuster which has been bled
of air in the cylinder head. d. Using the special tool, lower the valve and install
the roller rocker arm.
NOTE
To mount the roller rocker arm, first place the pivot
side of the rocker arm on the lash adjuster, then push
down the valve; next, place the slipper side of the
rocker arm on the valve system side.
ENGINE – Engine Adjustments
4. LASH ADJUSTER REPLACEMENT
Refer to (4) of the preceding paragraph.
5. IGNITION TIMING CHECK
Check that ignition timing is at the standard value.
Standard value: approx. 5_BTDC
NOTE Ignition timing is variable within about ±7_, even under normal operating.
11-7
Crank angle sensor connector
6. IDLE SPEED CHECK AND IDLE MIXTURE CHECK
(1) Run the engine at 2,000 to 3,000 r/min for 2 minutes. (2) Check the CO and HC contents at idle.
Standard value
CO contents: 0.6% or less HC contents: 300 ppm or less
7. COMPRESSION PRESSURE CHECK
(1) Before inspection, check that the engine oil, starter and
battery are normal. In addition, set the vehicle to the pre-inspection condition.
(2) Remove all of the spark plugs. (3) Disconnect the crank angle sensor connector.
NOTE Doing this will prevent the engine-ECU from carrying out ignition and fuel injection.
(4) Cover the spark plug hole with a shop towel etc., and
after the engine has been cranked, check that no foreign material is adhering to the shop towel.
Caution (1) Keep away from the spark plug hole when
cranking.
(2) If compression is measured with water, oil, fuel,
etc., that has come from cracks inside the cylinder, these materials will become heated and will gush out from the spark plug hole, which is dangerous.
11-8
Compression gauge
ENGINE – Engine Adjustments
(5) Set compression gauge to one of the spark plug holes. (6) Crank the engine with the throttle valve fully open and
measure the compression pressure.
Standard value
(at engine speed of 250 r/min): 11.5 kg/cm
Limit (at engine speed of 250 r/min): 9.7 kg/cm
2
2
(7) Measure the compression pressure for all the cylinders,
and check that the pressure differences of the cylinders are below the limit.
Limit: Max. 1.0 kg/cm
2
(8) If there is a cylinder with compression or a compression
difference that is outside the limit, pour a small amount of engine oil through the spark plug hole, and repeat the operations in steps (5) through (7). a. If the compression increases after oil is added, the
cause of the malfunction is a worn or damaged piston ring and/or cylinder inner surface.
b. If the compression does not rise after oil is added,
the cause is a burnt or defective valve seat, or pressure is leaking from the gasket.
(9) Connect the crank angle sensor connector. (10)Install the spark plugs. (11)Install the ignition coil and connect the ignition coil
connector.
(12)Erase the diagnosis codes by keeping the battery minus
(–) cable disconnected for more than 10 seconds. NOTE
This will erase the diagnosis code resulting from the crank angle sensor connector being disconnected.
Fuel pressure regulator valve
Vacuum gauge
8. MANIFOLD VACUUM CHECK
(1) Before inspection, set the vehicle to the pre-inspection
condition.
(2) Connect a tachometer connector. (3) Attach a three-way union to the vacuum hose between
the fuel pressure regulator valve and the intake manifold, and connect a vacuum gauge.
(4) Start the engine and check that idle speed is within
standard value.
Standard value: 850 ± 50 r/min
5. Check the manifold vacuum at idling.
Limit: Min. 55 kPa {410 mmHg}

"CA OIL RETURN PIPE GASKET INSTALLATION
Install the gasket with the printed portion toward the oil pan.
"DA HIGH-PRESSURE FUEL HOSE INSTALLATION
(1) Apply a small amount of new engine oil to the O-ring,
then fit the O-ring in the delivery pipe.
Caution Do not let any engine oil get into the delivery pipe.
(2) Check that the high pressure hose turns smoothly.
If the hose does not turn smoothly, the O-ring is probably being clamped. Disconnect the high-pressure fuel hose and check the O-ring for damage. After this, re-install the hose to the delivery pipe and check that the hose turns smoothly.
(3) Tighten the mounting bolts to the specification.

REMOVAL SERVICE POINTS
AA" TIMING BELT REMOVAL
(1) If the timing belt is to be reused, chalk an arrow mark
on the back surface of the belt so that the belt can be reinstalled in the same direction.
(2) Place the exhaust camshaft sprocket in a position where
the timing mark for No. 1 cylinder is positioned about one tooth before the top dead center of the compression stroke.
Caution The camshaft sprocket on the exhaust side can turn very easily because of the valve spring tension. Use care not to allow your fingers to get caught by the sprocket.
(3) Loosen the lock nut of the tensioner pulley, then remove
the timing belt.
AB" OIL PUMP SPROCKET REMOVAL
(1) Remove the plug on the left side of cylinder block. (2) Insert a screwdriver (shank diameter 8 mm) to block the
