TIMING CHAIN
Check for cracks (A) and any excessive wear (B) at link plates and
roller links of timing chain. Replace timing chain as necessary.
INSPECTION AFTER INSTALLATION
• Before starting engine, check oil/fluid levels incl
uding engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-14, "
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, che ck 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 gas, or any oils/fluids including engine oil and engine coolant.
• Bleed air from passages in lines and hoses, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to spec- ified level, if necessary.

3. Remove intake valve timing control solenoid valve. Refer to
EM-49, "Exploded View".
4. Crank engine, and then make sure that engine oil comes out from intake valve timing control solenoid valve hole (A). End
crank after checking.
WARNING:
Be careful not to touch rotating parts (drive belts, idler pul-
ley, and crankshaft pulley, etc.).
CAUTION:
• Prevent splashing by using a shop cloth so as to prevent the worker from injury from engine oil an d 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.
5. 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, and then clean it. Refer to EM-65, "
Inspection".
• Clean oil groove between oil strainer and intake valve timing control solenoid valve. Refer to LU-6,
"Engine Lubrication System" and LU-6, "Engine Lubrication System Schematic".
6. Remove components between intake valve timing control solenoid valve and camshaft sprocket (INT), and then check each oil groove for clogging.
• Clean oil groove if necessary. Refer to LU-6, "
Engine Lubrication System" and LU-6, "Engine Lubrica-
tion System Schematic".

4. Remove cylinder head loosening bolts in reverse order as
shown.
5. Remove cylinder head gasket.
INSPECTION AFTER REMOVAL
Cylinder Head Bolt s 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 appear s 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-116, "
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 passag es 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.
