The oil level between cold and warm oil will only measure the expansion of the oil itself as it heats up for the most part in a engine, but you should always check it within a few minutes of shut down warm or cold to ensure the oil gallies/filter are full and not drained back into the pan.
The Honda Kseries engines produce very high oil pressures during higher rpm useage at the main and rod bearings as they are prior to the VTC and VTEC systems which requires high oil pressures to operate. When this oil is forced out of the main/rod bearings it is under about twice the pressure seen in other engines, this causes the oil to mist/vaporize and is drawn thru the PCV into the intake mani and the majority is burned off and a smaller amount collects in the mani(remove the lower cover of the IM and a bunch of oil will be present). Installing a oil seperator between the PCV and the mani will collect all that oil, you will be amazed at how much is collected!!!!
