5. Perform the following inspection if engine oil does not
come out from valve timing control solenoid valve
oil hole of the valve timing control cover.
Remove oil filter, and then clean it. Refer to EM-61, "
Exploded View".
Clean oil groove between oil strainer and valve timing control solenoid valve. Refer to LU-5, "
Engine
Lubrication System" and LU-6, "Engine Lubrication System Schematic".
6. Remove components between valve timing control solenoid valve and camshaft sprocket, and then check each oil groove for clogging.
Clean oil groove if necessary. Refer to LU-5, "
Engine Lubrication System" and LU-6, "Engine Lubrica-
tion System Schematic".
7. After inspection, install removed parts in the reverse order.
Inspection for Leakage
The following are procedures for chec king fluid leakage, lubricant leakage.
Before starting engine, check oil/fluid levels including engine coolant and engine oil. If any are less than the
required quantity, fill them to the specified level. Refer to MA-10, "
Fluids and Lubricants".
Follow the procedure below to check for fuel leakage.
- Turn ignition switch to the “ON” position (with engi ne stopped). With fuel pressure applied to fuel piping,
check for fuel leakage 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 chain tensioner drops after removal/installation, slack in guide may generate a
pounding noise during and just after the engine start. However, this does not indicate a malfunction. The
noise will stop after hydraulic pressure rises.
Warm up engine thoroughly to check that there is no leak age 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 them to
the specified level, if necessary.
