| The slight noise produced by the valves upon starting the engine is normal. |
| –
| Start the engine and run it until the electric ventilator is turned on. |
| –
| Run the engine at 25000 RPM for 2 minutes. |
| If the pushers still produce noise, carry out the following sequence of operations to find the defective pusher: |
| –
| Remove the cylinder head cover. |
| –
| Turn the crankshaft clockwise (when looking from the cogwheel end), until the cams of the pushers to be tested are up. |
| Then measure any play between the cams and the pushers: |
| –
| If the measurement is any more than 0.1 mm then replace the pusher. |
| –
| If the measurement is less than 0.1 mm, continue the test. |
