CYLINDER HEAD

• If the calculated value exceeds the limit, replace valve and/or valve guide. When valve guide must be

replaced. Refer to

EM-187, "Disassembly and Assembly"

.

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-187, "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 valve spring pressure with valve spring seat installed at the

specified spring height.

CAUTION:

Never remove valve spring seat from valve spring.

• If the installation load or load with valve open is out of the stan-

dard, replace valve spring (with valve spring seat).

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-21, "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.

WARNING:

• Situate the vehicle on a flat and solid surface.
• Place chocks at front and back of rear wheels.
• Attach proper slingers and bolts described in PARTS CATALOG if engine slingers are not equipped.

CAUTION:

• Always be careful to work safely, avoid forceful or uninstructed operations.
• Never start working until exhaust system and coolant are cool enough.
• If items or work required are not covered by the engine section, refer to the applicable sections.
• Always use the support point specified for lifting.
• Use either 2-pole lift type or separate type lift as best you can. If board-on type is used for unavoid-

able reasons, support at the rear axle jacking point with a transmission jack or similar tool before
starting work, in preparation for the backward shift of center of gravity.

• For supporting points for lifting and jacking point at rear axle, refer to

GI-33, "Garage Jack and

Safety Stand and 2-Pole Lift"

.
