INSPECTION AFTER INSTALLATION
Inspection for Leaks
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-12, "
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.
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 an unusualness.
Noise will stop after hydraulic pressure rises.
Warm up engine thoroughly to make sure 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.

INSPECTION
Perform inspection as follows after removal, installation or replacement of camshaft or valve-related parts, or if
there is unusual engine conditions regarding valve clearance.
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 bank). Refer to EM-51, "
ROCKER COVER" .
2. Measure the valve clearance as follows:
a. Set No. 1 cylinder at TDC of its compression stroke.
Rotate crankshaft pulley clockwise to align timing mark
(grooved line without color) with timing indicator.
Make sure that intake and exhaust cam nose on No. 1 cylin-
der (engine front side of right bank) are located as shown in
the figure.
If not, turn crankshaft one revolution (360 degrees) and align
as shown in the figure.

e. Turn all cylinder head bolts 90 degrees clockwise (angle tighten-
ing).
CAUTION:
Check the tightening angle by using the angle wrench
(SST). Avoid judgment by visual inspection without SST.
Check tightening angle indicated on the angle wrench indica-
tor plate.
f. Turn all cylinder head bolts 90 degrees clockwise again (angle
tightening).
4. After installing cylinder head, measure distance between front
end faces of cylinder block and cylinder head (left and right
banks).
If measured value is out of the standard, re-install cylinder
head.
5. Install in the reverse order of removal after this step.
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-12, "
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

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.
