VALVE CLEARANCE INSPECTION [KJ]
1. Remove the intake manifold.
2. Remove the cylinder head cover.
3. Verify that the engine is cold.





4. Measure the valve clearance.

Standard [Engine cold]:
IN: 0.27 - 0.33 mm (0.011 - 0.012 inch)
EX: 0.27 - 0.33 mm (0.011 - 0.012 inch)

1. Turn the crankshaft clockwise so that the No.1 piston is at TDC of the compression stroke.








2. Measure the valve clearances at A in the figure.
3. If the valve clearance exceeds the standard, replace the adjustment shim.
4. Turn the crankshaft approx. 240° clockwise so that the No.3 piston is at TDC of the compression stroke.
5. Measure the valve clearances at B in the figure.
6. If the valve clearance exceeds the standard, replace the adjustment shim.
7. Turn the crankshaft approx. 240° clockwise so that the No.5 piston is at TDC of the compression stroke.
8. Measure the valve clearances at C in the figure.
9. If the valve clearance exceeds the standard, replace the adjustment shim.
5. Install the cylinder head cover.
6. Install the intake manifold.
