204-0856 front left camshaft group for engine spare part

Maintenance & Replacement Tips

1. When replacing the camshaft, simultaneously inspect the condition of the tappets, pushrods, and valve springs to prevent premature wear of the new component.
2. Clean the oil passages before installation, and apply the specified engine oil to the journals and cam lobes to provide pre-lubrication.
3. Set the valve timing strictly according to the service manual; any deviation can lead to a loss of power, abnormal noise, or even valve-to-piston contact.
4. After assembly, manually rotate the engine (crank it over by hand) to ensure there is no binding or resistance before attempting to start the engine.
