I have good oil pressure when engine is cold(40PSI). As temp rises the oil pressure drops. I replaced the oil pump but it did not help much.

If there's no engine knocking noises and you're reading off from the dash gauge-I suggest you use a mechanical gauge and hook it up to where the oil pressure switch and check it there-if its the mechanical gauge-try checking the oil pump.
