So last week I was driving my 73 400 Charger and got to a stop light. I was idling there for a bit and happened to glance down at my oil pressure gauge. As I was looking at it, it slowly crept from almost all the way up, which is where it usually is, to zero nothing. So I listened closer to the engine and it sounded the same as usual. I thought maybe the gauge just broke, I then gave it some gas and the pressure slowly climbed back up to normal and didn't drop again even after idling in my driveway for five minutes. I plan on driving the car further than I ever have before next week, 90 miles or 1.5 hours, but now I am unsure. Could this be a sign of an underlying problem?
