from the other three 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 a 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.
2. If wear exceeds the limit, replace camshaft.

Valve Lifter Clearance
VALVE LIFTER OUTER DIAMETER Measure the outer diameter at 1/2 height of valve lifter with a
micrometer (A) since valve lifter is in barrel shape.
VALVE LIFTER HOLE DIAMETER Measure the inner diameter of valve lifter hole of cylinder head with
an inside micrometer.
VALVE LIFTER CLEARANCE (Valve lifter clearance) = (Valve lifter hole diameter) – (Valve lifter outer diameter)
 If the calculated value is out of the standard, referring to each standard of valve lifter outer diameter and
valve lifter hole diameter, replace either or both valve lifter and cylinder head.
INSPECTION AFTER INSTALLATION
Inspection of Camshaft Sprocket (INT) Oil Groove
CAUTION:
 Perform this inspection only when DTC P0011 is detected in self-diagnostic results of CONSULT-III
and it is directed according to inspection procedure of EC section. Refer to EC-137, "
Diagnosis Pro-
cedure".
 Check when engine is cold so as to prevent burns from the splashing engine oil.
1. Check engine oil level. Refer to LU-7, "
Inspection".
2. Perform the following procedure so as to prevent the engine from being unintentionally started while
checking.

hand.
CAUTION:
When working, take care not to damage valve lifter holes.
5. Remove valve spring retainer, and valve spring.
6. Remove valve oil seal using the valve oil seal puller [SST:
KV10107902 (J38959)] (A).
INSTALLATION
1. Apply new engine oil on new valve oil seal joint and seal lip.
2. Using the valve oil seal drift [SST: KV10115600 (J-38958)] (A),
press fit valve seal to height (b) shown in the figure.
NOTE:
Dimension: Height measured before valve spring seat installa-
tion
