(3)

While cranking the engine, measure the compression pressure.
Compression pressure:
1.360 MPa (13.9 kgf/cm2, 198 psi)
Minimum pressure:
0.98 MPa (10 kgf/cm2, 142 psi)
Difference between each cylinder:
100 kPa (1.0 kgf/cm2, 14 psi)
NOTICE:
S
Always use a fully charged battery to obtain engine

speed of 250 rpm or more.
S
Check other cylinder’s compression pressure in the
same way.
S
This measurement must be done in as short a time as
possible.
(4) If the cylinder compression is low, pour a small
amount of engine oil into the cylinder through the
spark plug hole and inspect again.
HINT:
S
If adding oil increases the compression, it is likely that the
piston rings and/or cylinder bore are worn or damaged.
S
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) Race engine at 2,500 r/min for approx. 180 seconds.
(c) Insert CO/HC meter testing probe at least 40 cm (1.3 ft) into tailpipe during idling.
(d) Immediately check CO/HC concentration at idle and/or 2,500 r/min.
HINT:
S
Complete the measuring within 3 minutes.
S
When doing the 2 mode (idle and 2,500 r/min.) test, these measuring orders are prescribed by the applicable local regulations.
(e) If the CO/HC concentration does not comply with regulations, troubleshoot in the order given below.
(1) Check heated oxygen sensor operation. (See page 12–1)
(2) See the table below for possible causes, and then inspect and correct the applicable causes if

necessary.

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

Thickness of new lifter

B

Thickness of used lifter

C

Measured valve clearance

Valve clearance:
Intake A = B + (C – 0.24 mm (0.0094 in.))
Exhaust: A = B + (C – 0.35 mm (0.0138 in.))
EXAMPLE: (Intake)
Measured valve clearance = 0.44 mm (0.0173 in.)
0.44 mm (0.0173 in.) – 0.24 mm (0.0094 in.) = 0.20 mm (0.0079 in.)
(Measured – Specification = Excess clearance)
Used shim measurement = 5.30 mm (0.2087 in.)
0.20 mm (0.0079 in.) + 5.30 mm (0.2087 in.) = 5.50 mm (0.2165 in.)
(Excess clearance + Used shim = Ideal new shim)
Closest new shim = 5.50 mm (0.2165 in.) = Shim No. ”50”
(1) Select a new lifter with a thickness as close as possible to the calculated values.
