I was out driving in my car and heard a funny noise over behind the glove box. Kind of a muffled buzz. Then it stopped and the oil pressure gauge was reading zip. If I raced the engine a bit it would go up to about 1.5. I have full synthetic in it and the level of oil is correct. When I loosen the oil cover at idle there is oil flying all around. The car is running at a cool 80 degrees and idles around 800? What went?
