(d) Check the piston pin fit at room temperature.
Coat the piston pin with engine oil and push it into the con-
necting rod with your thumb.
15. INSPECT CONNECTING ROD BOLTS
Using vernier calipers, measure the minimum diameter of the
compressed bolt at the measuring point.
Standard diameter: 8.1 - 8.3 mm (0.319 - 0.327 in.)
Minimum diameter: 8.0 mm (0.315 in.)
If the diameter is less than minimum, replace the connecting rod
bolt.
16. INSPECT CRANKSHAFT FOR RUNOUT
(a) Place the crankshaft on V-blocks.
(b) Using a dial indicator, measure the circle runout at the
center journal.
Maximum circle runout: 0.06 mm (0.0024 in.)
If the circle runout is greater than maximum, replace the crank-
shaft.
17. INSPECT MAIN JOURNALS AND CRANK PINS
(a) Using a micrometer, measure the diameter of each main
journal and crank pin.
Diameter:
If the diameter is not as specified, check the oil clearance. (See
page EM-71)
(b) Check each main journal and crank pin for taper and out-
of-round as shown.
Maximum taper and out-of round:
0.02 mm (0.0008 in.)
If the taper or out-of-round is greater than maximum, grind or
replace the crankshaft.

(d) Using a pin hole grinder, bore the bushing to obtain the
standard specified clearance (See page EM-79) be-
tween the bushing and piston pin.
(e) Check the piston pin fit at room temperature.
Coat the piston pin with engine oil and push it into the con-
necting rod with your thumb.

COMPRESSION
INSPECTION
HINT:
If there is 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 normal operating temperature.
2. DISCONNECT CAMSHAFT POSITION SENSOR
CONNECTORS
3. REMOVE IGNITION COILS ASSEMBLIES
(See page IG-6)
4. REMOVE SPARK PLUGS
5. CHECK CYLINDER COMPRESSION
(a) Insert a compression tester into the spark plug hole.
(b) While cranking the engine, measure the compression
pressure.
HINT:
Always use a fully charged battery to obtain engine revolutions
of 250 rpm or more.
(c) Repeat steps (a) through (b) for each cylinder.
NOTICE:
This measurement must be done in as short a time as pos-
sible.
Standard pressure:
1,079 kPa (11.0 kgf/cm
2, 156 psi) or more
Minimum pressure:
883 kPa (9.0 kgf/cm
2, 128 psi)
Difference between each cylinder:
98 kPa (1.0 kgf/cm
2, 14 psi) or less
(d) If the cylinder compression in 1 or more cylinders is low,
pour a small amount of engine oil into the cylinder through
the spark plug hole and repeat steps (a) through (b) for
the cylinder with low compression.

If adding oil helps the compression, it is likely that
the piston rings and/or cylinder bore are probably
worn or damaged.

If pressure stays low, a valve may be sticking or
seating improper, or there may be leakage past the
gasket.

OIL AND FILTER
INSPECTION
1. CHECK OIL QUALITY
Check the oil for deterioration, entry of water, discoloring or thin-
ning.
If oil quality is visibly poor, replace the oil.
Oil grade (2JZ-GE):
API grade SH Energy-Conserving II or SJ, Energy-
Conserving or ILSAC multigrade engine oil.
SAE 5W-30 is the best choice for your vehicle, for
good fuel economy, and good starting in cold weath-
er.
Oil grade (2JZ-GTE):
API grade SH Energy-Conserving II or SJ, Energy-
Conserving or ILSAC multigrade engine oil.
Recommended viscosity is as shown in the illustra-
tion.
2. CHECK ENGINE OIL LEVEL
The oil level should be between the low level and full level marks
on the dipstick.
If low, check for the leakage and add oil up to full level mark.
3. REMOVE ENGINE UNDER COVER
4. 2JZ-GTE:
REMOVE NO.2 AIR TUBE
Loosen the 2 hose clamps, and remove 2 bolts and air tube.
5. 2JZ-GTE M/T:
REMOVE DRIVE BELT TENSION DAMPER
Remove the 2 nuts and tensioner damper.
6. REMOVE DRIVE BELT
Loosen the drive belt tension by turning the drive belt tensioner
clockwise, and remove the drive belt.
