b. Disconnect ignition coil and injector harness connectors. Refer to EM-49, "Exploded View" and EM-44,
"Exploded View".
3. Remove intake valve timing control solenoid valve. Refer to EM-79, "
Exploded View".
4. Crank engine, and then check 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 belt, 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 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 no to apply engine oil to rubber parts of drive belt,
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 LU-10, "
Removal and Installation".
Clean oil groove between oil strainer and intake valve timing control solenoid valve. Refer to LU-2,
"EngineLubricationSystem".
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-2, "
EngineLubricationSystem".
7. After inspection, install removed parts in the reverse order.
Inspection for Leakage
The following are procedures for checking fluids leak, lubricates leak. 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-11, "
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.
NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal/installation, slack in the guide may
generate a pounding noise during and just after engine start. However, this is normal. Noise will stop after
hydraulic pressure rises.
Warm up engine thoroughly to check there is no leakage of fuel, or any oil/fluids including 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.
Summary of the inspection items:
*: Transmission/transaxle/CVT fluid, power steering fluid, brake fluid, etc.1 : Valve timing control cover (bank 2)
