DON'T DRIVE IT WITH NO OIL PRESASURE!!!!If the lifters are quiet, it probably still has oil preasure but the sending unit is defective. Have a manual gauge installed temporarily to check the preasure. If ti stiil loesn't have preasure, it can be the pump or screen stopped up. The filter has a bypass to let it have preasure if it stops up. Dodge 3.9 has a week point at the far end of the cam shaft under the distributer where oil flow is minimal at best. over time this causes severly worn cam lobes and broken oil pump drive gears. if you pop off a valave cover and still see no signs of oil presure its definatelt time for some top end work.
