CONSULT-II and it is directed according to inspection procedure of EC section. Refer to 

EC-115,

"SELF-DIAG RESULTS MODE"

 .

Check when engine ins cold so as to prevent burns from any splashing engine oil.

1.

Check the engine oil level. Refer to 

LU-6, "ENGINE OIL"

 .

2.

Perform the following procedure so as to prevent the engine from being unintentionally started while
checking.

from camshaft bracket (No. 1) oil hole. End crank after checking.

WARNING:

Be careful not to touch rotating parts (drive belts, idler pul-
ley, and crankshaft pulley, etc.).

CAUTION:

Engine oil may squirt from intake valve timing control sole-
noid valve installation hole during cranking. Use a shop
cloth to prevent the engine components and the vehicle. Do
not allow engine oil to get on rubber components such as
drive belt or engine mount insulators. Immediately wipe off
any splashed engine oil.

Clean oil groove between oil strainer and intake valve timing control solenoid valve if engine oil does not
come out from camshaft bracket (No. 1) oil hole. Refer to 

LU-4, "LUBRICATION SYSTEM"

 .

NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal/installation, slack guide may gener-
ate 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 make sure there is no leakage of fuel, exhaust gases, 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.

INSPECTION

In cases of removing/installing or replacing camshaft and valve-
related parts, or of unusual engine conditions due to changes in
valve clearance (found malfunctions during stating, idling or causing
noise), perform inspection as follows:

1.

Remove rocker covers (right and left banks). Refer to 

EM-47, "ROCKER COVER"

 .

2.

Measure the valve clearance as follows:

a.

If compression pressure is below minimum value, check valve clearances and parts associated with
combustion chamber (valve, valve seat, piston, piston ring, cylinder bore, cylinder head, cylinder head
gasket). After the checking, measure compression pressure again.

If some cylinders have low compression pressure, pour small amount of engine oil into spark plug hole
of cylinder to re-check it for compression.

If the added engine oil improves the compression, piston rings may be worn out or damaged. Check
piston rings and replace if necessary.

If the compression pressure remains at low level despite the addition of engine oil, valves may be mal-
functioning. Check valves for damage. Replace valve or valve seat accordingly.

If two adjacent cylinders have respectively low compression pressure and their compression remains
low even after the addition of engine oil, cylinder head gaskets are leaking. In such a case, replace cyl-
inder head gaskets.

After inspection is completed, install removed parts.

10. Start the engine, and make sure that the engine runs smoothly.

INSPECTION AFTER INSTALLATION
Inspection for Leaks

The following are procedures for checking fluids leak, lubricates leak and exhaust gases 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-10, "RECOMMENDED 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
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.

Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gases, 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.
