| 1. |
Purpose of valve clearance inspection |
| (1) |
If the valve clearance is too large, any abnormal hitting
sound will become louder. |
| (2) |
If the valve clearance is too small, valve thermal expansion
after the engine warms up will cause the valve to strike the cam, which will prevent
the valve from closing. |
| |
| HINT: |
| Measure and adjust the valve clearance
while the engine is cold. |
