How do you adjust the valve clearances on the m102 engine. Actually i know how to but is it done with the engine hot or cold. Thanks?

Valve clearances on the M102 engine should be adjusted when the engine is cold, typically after it has been allowed to sit for several hours. This ensures that the metal components are at their contracted size, providing accurate measurements for the clearances. Always refer to the specific service manual for the exact specifications and procedures.
