in some engines, they have spec for hot and cold valve clearances.

if i am not mistaken, in the repair manual i used as i guide to adjust the valve clearance of a PH16, they specified the engine must be "cold" (let to stay cool overnight).

also, i think it will be difficult working with the valves if it is in normal operating temperature.
