Inspection Using Special Tools

CAUTION:
- Before using the Valve Inspection Tool, make sure that the air pressure gauge on the air compressor indicates over 400 kPa (4 kgf.cm, 57 psi).
- Inspect the valve clearance before rocker arm inspection.
- Cover the timing belt with a shop towel to protect the belt.
- Check the intake primary rocker arm of each cylinder at TDC.

1. Remove the cylinder head cover.





2. Plug the relief hole with the special tool.





3. Remove the sealing bolt from the inspection hole and connect an air pressure regulator with a 0 - 100 psi gauge.





4. Loosen the regulator valve on the valve inspection tool and apply the specified air pressure.

Specified Air Pressure: 250 kPa (2.5 kgf.cm, 36 psi)





5. Make sure that the intake primary and secondary rocker arms are mechanically connected by the piston and that the mid rocker arm does not move when pushed manually.
6. If any intake mid rocker arm moves independently of the primary and secondary rocker arms, replace the rocker arms as a set.
7. Remove the special tools.





8. Use a 10 mm diameter rod to depress each lost motion assembly through its full movement. Replace any lost motion assembly that does move smoothly.
9. After inspection, check that the MIL does not come on.
