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.
maybe nga in some engines, in my Lancer 4G92 kasi when we adjust the valves pinapainit muna namin yung makina, then turn-off, then let it cool a bit, then we open it and do the adjustment while the engine is still warm.

well anyway, different engines, different treatment I guess.

thanks
