INSPECTION AFTER REMOVAL
Camshaft Runout
1. Put V-block on precise flat table, and support No. 2 and 4 journal
of camshaft.
CAUTION:
Do not support journal No. 1 (on the side of camshaft
sprocket) because it has a different diameter from the other
three locations.
2. Set dial indicator vertically to No. 3 journal.
3. Turn camshaft to one direction with hands, and measure cam-
shaft runout on dial indicator. (Total indicator reading)
4. If it exceeds the limit, replace camshaft.
Camshaft Cam Height
1. Measure camshaft cam height with micrometer.
2. If wear is beyond the limit, replace camshaft.

–Dimension “B” for cylinder head No. 1 journal bearing.

Refer to the standards above, and then replace camshaft and/or
cylinder head.
Camshaft Sprocket Runout
1. Put V-block on precise flat table, and support No. 2 and 4 journal of camshaft.
CAUTION:
Do not support journal No. 1 (on the side of camshaft sprocket) because it has a different diameter
from the other three locations.
2. Measure the camshaft sprocket runout with 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-202,

REMOVAL
1. Remove engine assembly from vehicle, and separate front suspension member and transaxle from
engine. Refer to EM-223, "
ENGINE ASSEMBLY" .
2. Install engine sub-attachment with engine stand shaft [SST: KV10117001 and KV10106500] to right side
of cylinder block, then lift engine, and mount it onto engine stand [SST: ST0501S000]. Refer to EM-228,
"CYLINDER BLOCK" .
3. Remove camshaft relating to valve oil seal to be removed. Refer to EM-192, "
CAMSHAFT" .
4. Remove valve lifters. Refer to EM-192, "
CAMSHAFT" .
5. Rotate crankshaft until the cylinder requiring new oil seals is at TDC. This will prevent valve from dropping
into cylinder.
6. Remove valve collet.

Compress valve spring with valve spring compressor, attach-
ment, adapter (SST). Remove valve collet with magnet hand.
CAUTION:
When working, take care not to damage valve lifter holes.
7. Remove valve spring retainer and valve spring.
8. Remove valve oil seal using valve oil seal puller (SST).
INSTALLATION
1. Apply engine oil on new valve oil seal joint and seal lip.
2. Using valve oil seal drift (SST), press-fit valve seal to height “H”
shown in the figure.
NOTE:
Dimension “H”: Height measured before valve spring seat instal-
lation
