INSPECTION AFTER REMOVAL
Cylinder Head Bolts Outer Diameter
 Cylinder head bolts are tightened by plastic zone tightening
method. Whenever the size difference between “d1” and “d2”
exceeds the limit, replace them with a new one.
 If reduction of outer diameter appears in a position other than “d2”,
use it as “d2” point.
Cylinder Head Distortion
NOTE:
When performing this inspection, cylinder block distortion should be also checking. Refer to EM-127, "
Cylinder
Block".
1. Wipe off engine oil and remove water scale (like deposit), gasket, sealant, carbon, etc. with a scraper.
CAUTION:
Never allow gasket debris to enter passages for engine oil or engine coolant.
2. At each of several locations on bottom surface of cylinder head,
measure the distortion in six directions.
 If it exceeds the limit, replace cylinder head.
INSTALLATION
1. Install new cylinder head gasket.
2. Tighten cylinder head bolts in numerical order as shown with the
following procedure to install cylinder head.
CAUTION:
If cylinder head bolts are re-used, check their outer diame-
ters before installation. Follow the “Cylinder Head Bolts
Outer Diameter” measurement procedure.
a. Apply new engine oil to threads and seating surfaces of mount-
ing bolts.
b. Tighten all bolts.
c. Completely loosen.
CAUTION:Limit (“d1”–“d2”): 0.15 mm (0.0059 in)

In this step, loosen bolts in reverse order of that indicated.
d. Tighten all bolts.
e. Turn all bolts 75 degrees clockwise (angle tightening).
CAUTION:
Check and confirm the tightening angle by using the angle
wrench [SST: KV10112100] (A) or protractor. Avoid judg-
ment by visual inspection without the tool.
f. Turn all bolts 75 degrees clockwise again (angle tightening).
3. Installation is in the reverse order of removal, for the remaining parts.
INSPECTION AFTER INSTALLATION
Inspection for Leaks
 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-19, "
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 make sure there is no leakage of fuel, exhaust gases, or any oil/fluids includ-
ing 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.

6. Remove valve oil seal with the valve oil seal puller [SST:
KV10107902] (A).
7. Remove valve spring seat.
8. Remove valve seat, if valve seat must be replaced.
 Bore out old seat until it collapses. Boring should not continue beyond the bottom face of the seat
recess in cylinder head. Set the machine depth stop to ensure this.
CAUTION:
Never bore excessively to prevent cylinder head from scratching.
9. Remove valve guide, if valve guide must be replaced.
a. To remove valve guide, heat cylinder head to 110 to 130°C (230
to 266°F) by soaking in heated oil (A).
b. Drive out valve guide with a press [under a 20 kN (2 ton, 2.2 US
ton, 2.0 lmp ton) pressure] or a hammer and the valve guide drift
(commercial service tool).
WARNING:
Cylinder head contains heat. Wear protective equipment to
avoid getting burned.
INSPECTION AFTER DISASSEMBLY
Valve Dimensions
 Check the dimensions of each valve. For the dimensions, refer to EM-125, "Cylinder Head".
 If dimensions are out of the standard, replace valve and check valve seat contact. Check “VALVE SEAT
CONTACT”.
