Oil pressure nosedive
Oops. While driving towards my driveway (~20 MPH), I shifted it into neutral, and then reverse just after I pass it so I can back in. Normally, I let the car stop or slow down to 5-10 MPH before shifting from neutral to reverse, but today I was in a rush, so I (stupidly) shifted it into reverse at like 15-20 MPH. (stupid stupid stupid...) I just feel a clunk and the oil pressure just drops instantly from ~30 PSI to zero. The car dings as the check gauges light comes on, and I freak out and kill the engine. Nothing else happened--no check engine light, no sound of oil-less engine... nothing.
I restart the engine a few seconds later and the oil pressure'* fine. What happened there? It runs fine as if it never happened at all.
