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 checked. Refer to 

EM-123, "Inspec-

tion"

.

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 water.

2. At each of several locations on bottom surface of cylinder head,

measure the distortion in six directions using straightedge (A)

and feeler gauge (B).

• If it exceeds the limit, replace cylinder head.

INSPECTION AFTER DISASSEMBLY

VALVE DIMENSIONS

• Check the dimensions of each valve. For the dimensions, refer to 

EM-142, "Cylinder Head"

.

• If dimensions are out of the standard, replace valve and check valve seat contact. Refer to “VALVE SEAT

CONTACT”.

VALVE GUIDE CLEARANCE

Valve Stem Diameter

• Measure the diameter of valve stem with micrometer (A).

Valve Guide Inner Diameter

• Measure the inner diameter of valve guide with bore gauge.

Valve Guide Clearance

• (Valve guide clearance) = (Valve guide inner diameter) – (Valve

stem diameter)

Limit [(d1) – (d2)]: 0.15 mm (0.0059 in)
