I have a leak coming from the left front side of the engine (sitting in the Driver seat). The leak appears to be coming from the oil pan there ar drips on the oil pan bolts. Upon a closer look the top of the power steering box is also coated with significant oil. I cannot tell if it is oil or PS fluid. Both fluids in this truck are clear/yellow (oil color) and smell is close but I still can't tell. Do any of you have a method for finding a leak?
