What do you mean by loud... Loud where??? If noise is from engine, make sure that the mechanical fan clutch is not "locked" (it's supposed to freewheel when cold... if it does not, it will "roar" when driving.

Sorry to say it sounds like the motor is gone. Higher oil pressure when the oil is cold is normal. But, when the engine gets to operating temp and the pressure bottoms out and the engine knocks you have big problems. If the mileage is very high (150,000) or more your bearings are so worn that the oil can't fill the void between the surfaces and thus the low oil pressure.

Move it to 3rd instead of drive and see if you still have the noise. May be transmission related since you have replaced everything else.
