When performing a valve adjustment, always ensure the engine is cold and follow the specific torque specifications found in your service manual. It is recommended to measure clearances accurately with a feeler gauge before selecting the appropriate shim thickness. Replacing worn or incorrect shims is a standard part of routine top-end maintenance.
