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.

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”.

Valve Guide Clearance (Valve guide clearance) = (Valve guide inner diameter) – (Valve
stem diameter)
If the calculated value exceeds the limit, replace valve and/or valve guide. When valve guide must be
replaced, use “VALVE GUIDE REPLACEMENT”.
Valve Seat Contact
After confirming that the dimensions of valve guides and valves are
within the specifications, perform this procedure.
Apply prussian blue (or white lead) onto contacting surface of valve
seat to check the condition of the valve contact on the surface.
Check if the contact area band is continuous all around the circum-
ference.
If not, grind to adjust valve fitting and check again. If the contacting
surface still has “NG” conditions even after the re-check, replace
valve seat. Refer to EM-82, "
Disassembly and Assembly".
Valve Spring Squareness
Set a try square (A) along the side of valve spring and rotate
spring. Measure the maximum clearance between the top of spring
and try square.
If it exceeds the limit, replace valve spring.
Valve Spring Dimensions and Valve Spring Pressure Load
Check the valve spring pressure at specified spring height.
If the installation load or load with valve open is out of the stan-
dard, replace valve spring.
ASSEMBLY
1. When valve guide is removed, install it.
