Knocking sound in a 1996 5.7l vortec

텍스트:

I don’t have any problems out of the motor, when it’s cold, but when it warms up a knock starts and it goes from 40 pounds of oil pressure to when warm about 0-20 idling or moving and the more gas i give it the louder the knock is and it lowers the oil pressure.
