INSPECTION AFTER INSTALLATION
Inspection for Leakage
The following are procedures for checking fluids leak, lubricates leak and exhaust gases leak.
 Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-11, "
Fluids and Lubricants".
 Use procedure below to check for fuel leakage.
- Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leak-
age at connection points.
- Start engine. With engine speed increased, check again for fuel leakage at connection points.
 Run engine to check for unusual noise and vibration.
 Warm up engine thoroughly to check there is no leakage of fuel, exhaust gases, or any oil/fluids including
engine oil and engine coolant.
 Bleed air from lines and hoses of applicable lines, such as in cooling system.
 After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the
specified level, if necessary.
Summary of the inspection items:
*: Transmission/transaxle/CVT fluid, power steering fluid, brake fluid, etc.: Vehicle front

other contamination.
CAUTION:
Be careful not to allow gasket flakes to enter engine oil or engine coolant passages.
 Measure the distortion on the cylinder block upper face at some
different points in six directions (C), (D), (E), (F), (G) and (H) with a
straightedge (A) and a feeler gauge (B).

 If the measured value exceeds the limit, or if there are scratches
and/or seizure on the cylinder inner wall, hone or rebore the inner
wall.
 Oversize piston is provided. When using oversize piston, rebore
cylinder so that the clearance of the piston to cylinder bore satis-
fies the standard.
CAUTION:
When using oversize piston, use oversize pistons for all cylin-
ders with oversize piston rings.
Piston Skirt Diameter
Measure the outer diameter of piston skirt with a micrometer (A).
Piston-to-Cylinder Bore Clearance
Calculate by piston skirt diameter and cylinder bore inner diameter [direction (B), position (D)].
(Clearance) = (Cylinder bore inner diameter) – (Piston skirt diameter).
 If the calculated value exceeds the limit, replace piston and piston pin assembly. Refer to EM-129, "
Piston".
Reboring Cylinder Bore
1. Cylinder bore size is determined by adding piston to cylinder bore clearance to piston skirt diameter.
2. Install main bearing caps and main bearing beam, and tighten to the specified torque. Otherwise, cylinder
bores may be distorted in final assembly.
3. Cut cylinder bores.
NOTE:
 When any cylinder needs boring, all other cylinders must also be bored.
 Do not cut too much out of cylinder bore at a time. Cut only 0.05 mm (0.0020 in) or so in diameter at a
time.
4. Hone cylinders to obtain the specified piston to cylinder bore clearance.
5. Measure finished cylinder bore for the out-of-round and taper.
NOTE:
Measurement should be done after cylinder bore cools down.

 If out of the standard, measure the main bearing oil clearance. Then use undersize bearing. Refer to EM-
132, "MainBearing".
CRANKSHAFT PIN JOURNAL DIAMETER
 Measure the outer diameter of crankshaft pin journal with a
micrometer (A).
 If out of the standard, measure the connecting rod bearing oil
clearance. Then use undersize bearing. Refer to EM-130,
"ConnectingRodBearing".
CRANKSHAFT OUT-OF-ROUND AND TAPER
 Measure the dimensions at four different points as shown in the
figure on each main journal and pin journal with a micrometer.
 Out-of-round is indicated by the difference in the dimensions
between (d) and (c) at (a) and (b).
 Taper is indicated by the difference in the dimensions between.
 If the measured value exceeds the limit, correct or replace crank-
shaft.
 If corrected, measure the bearing oil clearance of the corrected
main journal and/or pin journal. Then select the main bearing and/
or connecting rod bearing. Refer to EM-132, "
MainBearing" and/
or EM-130, "
ConnectingRodBearing".
CRANKSHAFT RUNOUT
 Place V-block on precise flat table, and support the journals on the both end of crankshaft.

dial indicator. (Total indicator reading)
 If it exceeds the limit, replace crankshaft.
