INSPECTION AFTER REMOVAL
Oil Filter
• Make sure that there is no foreign material on the oil filter (1) and check it for clogging.
• Check the oil filter (1) for damage.
• If there is some damage, replace t he oil filter (1), the plug, and the
washer as a set.
CAUTION:
Do not reuse the washer.
Camshaft Runout
1. Put V-block on a precise flat table, and support No. 2 and 5 jour- nals of camshaft.
CAUTION:
Never support No. 1 journal (on the side of camshaft
sprocket) because it has a different diameter from the other
four locations.
2. Set a dial indicator vertically to No. 3 journal.
3. Turn camshaft to one direction with hands, and measure the camshaft runout on the dial indicator. (Total indicator reading)
4. If it exceeds the limit, replace camshaft.
Camshaft Cam Height
1. Measure the camshaft cam height with a micrometer (A).
2. If wear exceeds the limit, replace camshaft.

Never support No. 1 journal (on the side of camshaft sprocket) because it has a different diameter
from the other four locations.
2. Measure the camshaft sprocket runout with a dial indicator. (Total indicator reading)
• If it exceeds the limit, replace camshaft sprocket.
Valve Lifter
Check if surface of valve lifter has any wear or cracks.
• If anything above is found, replace valve lifter. Refer to EM-112,
"Camshaft".

4. Remove cylinder head loosening bolts in reverse order as
shown.
5. Remove cylinder head gasket.
INSPECTION AFTER REMOVAL
Cylinder Head Bolt s Outer Diameter
• Cylinder head bolts are tightened by plastic zone tightening
method. Whenever the size difference between “d1” and “d2”
exceeds the limit, replace them with a new one.
• If reduction of outer diameter appear s in a position other than “d2”,
use it as “d2” point.
Cylinder Head Distortion
NOTE:
When performing this inspection, cylinder block distortion should be also checking. Refer to EM-116, "
Cylinder
Block".
1. Wipe off engine oil and remove water scale (like deposit ), gasket, sealant, carbon, etc. with a scraper.
CAUTION:
Never allow gasket debris to enter passag es for engine oil or engine coolant.
2. At each of several locations on bottom surface of cylinder head, measure the distortion in six directions.
• If it exceeds the limit, replace cylinder head.
INSTALLATION
1. Install new cylinder head gasket.

CAUTION:
Check and confirm the tightening angle by using To ol (A) or protractor. Avoid judgment by visual
inspection without the tool.
