Hi, I drive a 2005 Nissan Pathfinder SE and when I first bought it, it had a timing chain issue. After fixing the problem, I had very low oil pressure (this could have been a problem before I had bought it and I never noticed). I tried my go at waiting till it got better but then it got worst. There was other problems with the engine so finally we rebuilt the motor. At this point I'm 3 grand in, freshly machined motor inside of the car with a brand new expensive oil pump and after 120 miles of break in, the oil light comes back on. Everything about the engine was perfect and 3 mechanically trained people put it together. At this point I'm stuck not knowing what to do. Everything oil related was fixed, even the passage was and I just don't know what to do. The light only comes on when I am stuck at a stop light, and then goes away when I start driving. What can I do?
