COMPRESSION
INSPECTION
HINT:
If there is a lack of power, excessive oil consumption or poor fuel
economy, measure the compression pressure.
1. WARM UP AND STOP ENGINE
Allow the engine to warm up to the normal operating tempera-
ture.
2. REMOVE SPARK PLUGS
(See page IG-1)
3. CHECK CYLINDER COMPRESSION PRESSURE
(a) Insert a compression gauge into the spark plug hole.
(b) Fully open the throttle.
(c) While cranking the engine, measure the compression
pressure.
HINT:
Always use a fully charged battery to obtain the engine speed
at 250 rpm or more.
(d) Repeat steps (a) to (c) for each cylinder.
NOTICE:
This measurement must be done as quickly as possible.
Compression pressure:
1,324 kPa (13.5 kgf/cm
2, 192 psi) or more
Minimum pressure:
981 kPa (10.0 kgf/cm
2, 142 psi)
Difference between each cylinder:
98 kPa (1.0 kgf/cm
2, 14 psi) or less
(e) If the cylinder compression in one or more cylinders is
lower than the specification, pour a small amount of en-
gine oil into the cylinder through the spark plug hole and
repeat steps (a) to (c) for the cylinders.
If adding oil helps the compression, chances are
that the piston rings and/or cylinder bore are worn
or damage.
If the pressure stays low, a valve may be sticking or
the seating is improper, or there may be leakage
past the gasket.
4. REINSTALL SPARK PLUGS

(f) Lay a strip of plastigage across the crank pin.
(g) Install the connecting rod cap with the 2 bolts.
(See page EM-107)
NOTICE:
Do not turn the crankshaft.
(h) Remove the 2 bolts, the connecting rod cap and the lower
bearing. (See procedure (b) and (c) above)
(i) Measure the plastigage at its widest point.
Standard oil clearance:
0.027 - 0.053 mm (0.0011 - 0.0021 in.)
Maximum oil clearance: 0.065 mm (0.0026 in.)
If the oil clearance is greater than the maximum, replace the
bearings. If necessary, replace the crankshaft.
HINT:
If using a standard bearing, replace it with the one having the
same number. If the number of the bearing cannot be deter-
mined, sum up the numbers imprinted on the connecting rod
cap and the crankshaft, then select the one with the same num-
ber as the total. There are 6 sizes of standard bearings, marked
º2º, º3º, º4º, º5º, º6º and º7º.
