WAR NIN G:
Be careful not to touch rotating parts (drive belts, idler pulley, and crankshaft pulley, etc.).
CAUTION:

Do not perform cranking without installing right engine mount bracket, right engine mount insu-
lator, and right torque rod.

Prevent splashing by using a shop cloth so as to prevent the worker from injury from engine oil
and so as to prevent engine oil contamination.

Prevent splashing by using a shop cloth so as to prevent engine oil from being splashed to
engine and vehicle. Especially, be careful not to apply engine oil to rubber parts of drive belts,
engine mounting insulator, etc. Wipe engine oil off immediately if it is splashed.
7. Perform the following inspection if engine oil does not come out from intake valve timing control solenoid
valve oil hole of the cylinder head.

Remove oil filter (for intake valve timing control), and then clean it. Refer to EM-77, "Components" .

Clean oil groove between oil strainer and intake valve timing control solenoid valve. Refer to LU-4,
"LUBRICATION SYSTEM" .
8. Remove components between intake valve timing control solenoid valve and camshaft sprocket (INT),
and then check each oil groove for clogging.

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-98, "
CYLIN-
DER BLOCK TOP SURFACE DISTORTION" .
1. Wipe off engine oil and remove water scale (like deposit), gasket, sealant, carbon, etc. with a scraper.
CAUTION:
Use utmost care not to 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.
