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, 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 leak age 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.

• Front cover, timing chain and related parts. Refer to EM-159
.
• Generator. Refer to SC-25, "
Removal and Installation".
7. Remove camshaft position sensor (PHASE) from camshaft bracket. CAUTION:
• Handle carefully to avoid dropping and shocks.
• Never disassemble.
• Never allow metal powder to adhere to magnetic part at sensor tip.
• Never place sensor in a location wher e it is exposed to magnetism.
8. Put matching marks (A) on the camshaft sprocket (INT) (2) and the camshaft bracket (1) as shown.
NOTE:
It prevents the knock pin of the camshaft (INT) from engaging
with the incorrect pin hole when installing the camshaft sprocket
(INT).
9. Remove camshaft sprockets (INT) (1) and (EXH) (2). • Secure hexagonal part (A) of camshaft with a wrench. Loosen
camshaft sprocket bolts and remove camshaft sprocket.
CAUTION:
• Never rotate crankshaft or camshaft while timing chainis removed. It causes interference between valve and
piston.
• Never loosen the bolts with securing anything other
than the camshaft hexagonal part or with tensioning the
timing chain.
10. Loosen bolts in reverse order as shown.
11. Cut liquid gasket by prying the position ( ) shown, and then remove the camshaft bracket.
CAUTION:
• Be careful not to damage the mating surface.

• Perform this inspection only when DTC P0011 is detected in self-diagnostic results of CONSULT-III
and it is directed according to inspect ion procedure of EC section. Refer to EC-647, "
Diagnosis Pro-
cedure".
• Check when engine is cold so as to pr event burns from the splashing engine oil.

4. Clean the mating area of intake valve timing control solenoid
valve. Insert a clean shop cloth (with no oil adhesion) into the oil
hole (A) of the cylinder head.
5. Install engine mounting bracket (RH), engine mounting insulator, and torque rod (RH) under the Step 4 condition. (With intake
valve timing control solenoid valve removed, and a shop cloth
inserted into the oil hole.) Refer to EM-197, "
Component".
6. Crank engine, and then make sure that engine oil comes out from intake valve timing control solenoid valve hole (A). End cranking after checking.
• Check engine oil leakage by oil amount adhered to the shop cloth inserted into the oil hole.
WARNING:
• Be careful not to touch rotating parts (drive be lts, idler pulley, and crankshaft pulley, etc.).
• Prevent splashing by using a shop cloth so as to prevent the worker from injury from engine oil
and so as to prevent engi ne oil contamination.
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 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 engi ne 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-202, "
Component".
• Clean oil groove between oil strainer and intake valve timing control solenoid valve. Refer to LU-16
.
8. Remove components between intake valve timing c ontrol solenoid valve and camshaft sprocket (INT),
and then check each oil groove for clogging.
• Clean oil groove if necessary. Refer to LU-16
.
