My Camaro's oil pressure drops to zero when it is at idle speed. When accelerating it, it only reaches a quarter of the pressure and, both at low or high speeds, the engine sounds as if it were not greased enough. I checked and found that it is the crankshaft that is making the noise. I don't know what is failing.

The stereo system, gas gauge, speedometer, oil pressure, trans temperature, electric gauge, interior screen all went nil at the same time.
