1993 90s no oil pressure to top of motor
I have a 1993 90s i went to start it one day and it started to knock being a mechanic i instantly knew oil. I checked the pressure at the oil sending unit and there was no pressure so i checked the oil pump and it seemed to be working fine. Just to be safe i tryed changing it and that didnt help.There are no clogged screens or hoses. If theres no pressure at the sending unit obviosly you have to trace the problem backwards but the sending unit is mounted to the oil pump and cant go any farther back. Im not that familiar with audi repair mainly american so im getting very frustrated any ideas. Please help!!!
