COMPRESSION PRESSURE

INSPECTION

EBCD8F14

NOTE

If the there is lack of power, excessive oil consump-
tion or poor fuel economy, measure the compression
pressure.

Warm up the engine until the normal operating tem-
perature becoming 80~95 C(176~203 F).

Remove the surge tank.

Remove the ignition coil connectors(A) and ignition
coils(B).

SCMEM6001L

Using a 16mm plug wrench, remove the 6 spark plugs.

Check cylinder compression pressure.

Insert a compression gauge into the spark plug
hole.

Open the throttle fully.

With the fully-open throttle in cranking, measure
the compression pressure.

NOTE

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

Repeat steps 1) through 3) for each cylinder.

NOTE

This measurement must be done in as short a time as
possible.

Compression pressure: 1,176.79kPa (12.0kgf/cm²,
170.68psi) - 200 ~ 250rpm
Minimum pressure: 1,029.69kPa (10.5kgf/cm²,
149.34psi)
Difference between cylinders: 98.07kPa
(1.0kgf/cm², 14.22psi)

If the compression pressure in 1 or more cylin-
ders is lower than the specification above, pour
a small amount of engine oil into the cylinder
through the spark plug hole, repeat the steps (1)
through (3) for the cylinder and measure the pres-
sure again.

• If adding oil increases the pressure up, the

piston rings or cylinder bores might be worn
or damaged.

• If the pressure doesn’t increase, a valve may

be sticking or seating may be improper, or
there may be leakage from the gasket.

Reinstall the spark plugs.

Install the ignition coils and connect ignition coil con-
nectors.

Install the surge tank.

VALVE CLEARANCE INSPECTION AND
ADJUSTMENT

NOTE

Inspect and adjust the valve clearance when
the engine is cold (Engine coolant temperature :
20 C±5 C(59~77 F)) and cylinder head is installed
on the cylinder block.

Remove the engine cover.

Remove air cleaner assembly.

Remove the surge tank.

Remove the cylinder head cover.

Disconnect the ignition coil connector and re-
move the ignition coil.

Remove the cylinder head cover.

KCBF177A

Set the piston of the No.1 cylinder to TDC(Top Dead
Center) position.

Turn the crankshaft pulley clockwise and align
its groove with the timing mark "T" of the timing
chain cover.

Check that the timing marks of the camshaft
sprocket are in straight line on that of the cylinder
head cover surface as shwn in the illustration. It
makes the piston of the No.1 cylinder position at
TDC.

KCBF119B

NOTE

If not, turn the crankshaft one revolution clockwise.

Inspect the intake and the exhaust valve clearance.

With the piston of the No.1 cylinder positioning
at TDC, the valves which can be measured its
clearance are as shown below.

Measurement method.

• Using a thickness gauge, measure the clear-

ance between the tappet and the base circle
of camshaft.

• Record the out-of-specification valve clear-

ance measurements. They will be used later
to determine the required adjusting tappet
for replacement.

Specification
Limit (Engine coolant temperature : 20 C [68 F])
Intake : 0.10 ~ 0.30mm (0.0039 ~ 0.0118in.)
Exhaust : 0.20 ~ 0.40mm (0.0079 ~ 0.0157in.)

EMA -10

ENGINE (G6EA - GSL 2.7)

Turn the crankshaft pulley one revolution (360 )
clockwise and align the groove with the timing
mark "T" of the timing chain cover.

With the piston of the No.4 cylinder positioning
at TDC, the valves which can be measured its
clearance are as shown below.

RH EXHAUST

LH EXHAUST

INTAKE

LDLG031A

Adjust the intake and the exhaust valve clearances.

Set the piston of the No.1 cylinder to the TDC/po-
sition.

Remove the timing belt.

Remove the camshaft bearing caps(A, B).

KCBF169A

Remove the camshaft assembly.

Remove MLA(Mechanical Lash Adjuster)s.

Measure the thickness of the removed tappet us-
ing a micrometer.

EDKE889D

Calculate the thickness of a new tappet so that
the valve clearance comes within the specified
value.

T : Thickness of removed tappet
A : Measured valve clearance
N : Thickness of new tappet
Intake : N = T + [A - 0.20mm(0.0079in.)]
Exhaust : N = T + [A - 0.30mm (0.0118in.)]

Select a new tappet with a thickness as close as
possible to the calculated value.

NOTE

Tappets are available with 41different size increments
of 0.015mm (0.0006in.) from 3.00mm (0.118in.) to
3.600mm (0.1417in.)

Place a new tappet on the cylinder head.

NOTE

Apply engine oil on the periphery surface of the se-
lected tappet.

10) Install the intake and exhaust camshafts.

11) Install the bearing caps.

12) Install the timing belt.

13) Turn the crankshaft two revolutions in the oper-

ating direction(clockwise) and realign crankshaft
sprocket and camshaft sprocket timing marks(A).

14) Recheck the valve clearance.

Specification (Engine coolant temperature: 20 C[68 F])
Intake : 0.17 ~ 0.23mm (0.0067 ~ 0.0090in.)
Exhaust : 0.27 ~ 0.33mm (0.0106 ~ 0.0129in.)
