NOTICE:

In case of having the injection pump replaced, must
replace the 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.

brackets and cylinder head cover.
8. REMOVE ENGINE UNDER COVER SUB±ASSY NO.1
9. REMOVE ENGINE UNDER COVER RH
10. SET NO. 1 CYLINDER TO TDC/COMPRESSION
(a) Turn the crankshaft pulley, and align the timing notch with
timing mark º0º of the timing chain cover.
(b) Check that the point marks of the camshaft timing sprock-
et and VVT timing sprocket are in straight line on the tim-
ing chain cover surface as shown in the illustration.
HINT:
If not, turn the crankshaft 1 revolution (360
) and align the
marks as above.
11. INSPECT VALVE CLEARANCE
(a) Check the valves indicated in the illustration.
(1) Using a feeler gauge, measure the clearance be-
tween the valve lifter and the camshaft.
(2) Record the out±of specification valve clearance
measurements. They will be used later to determine
the required replacement valve lifter.
Valve clearance (Cold):
Intake 0.15 to 0.25 mm (0.0059 to 0.0098 in.)
Exhaust 0.25 to 0.35 mm (0.0098 to 0.0138 in.)

inder to TDC/compression.
(c) Check the valves indicated in the illustration.

(3) While cranking the engine, measure the compres-
sion pressure.
Compression pressure


1,300 kPa (13.3 kgf
cm
2, 189 psi)
Minimum pressure: 1,000 kPa (10.2 kgf
cm
2, 145 psi)
Difference between each cylinder:
100 kPa (1.0 kgf
cm
2, 14 psi)
NOTICE:

Always use a fully charged battery to obtain engine
speed of 250 rpm or more.

Check other cylinder's compression pressure in the
same way.

This measurement must be done in as short a time as
possible.
(4) If the cylinder compression in one or more cylinders
is low, pour a small amount of engine oil into the cyl-
inder through the spark plug hole and repeat steps
(1) through (3) for the cylinders that have low com-
pression.
HINT:

If adding oil helps increase the compression, the piston
rings and/or cylinder bore may be worn or damaged.

If pressure stays low, a valve may be sticking or seating
improperly, or there may be leakage past the gasket.
10. INSPECT CO/HC
(a) Start the engine.
(b) Run the engine at 2,500 rpm for approximately 180 seconds.
(c) Insert CO/HC meter testing probe at least 40 cm (1.3 ft) into the tailpipe during idling.
(d) Check CO/HC concentration at idle.
Idle CO concentration: 0 to 0.5 %
Idle HC concentration: Applicable local regulation
If the CO/HC concentration does not conform to specifications, perform troubleshooting in the order given
below.

Check heated oxygen sensor operation.

See the table below for possible causes, and then inspect and repair the applicable causes if
necessary.

et and VVT timing sprocket are in straight line on the tim-
ing chain cover surface as shown in the illustration.
HINT:
If not, turn the crankshaft 1 revolution (360

13. REMOVE V±RIBBED BELT TENSIONER ASSY
(a) Remove the bolt and nut, then remove the V±ribbed belt
tensioner.
HINT:
Jack up and down to remove the bolt.
14. REMOVE CAMSHAFT
NOTICE:
Do not revolve the crankshaft without the chain tensioner.
(a) Set the No. 1 cylinder to the TDC/compression.
(b) Place match marks on the timing chain and the camshaft
timing sprockets.
(c) Remove the 2 nuts and the chain tensioner.
