I was at a stoplight. It just started making a grinding noise (probably the cylinders slapping the valves). I was not far from my regular repair shop, and drove it there. Later on, I returned to gather my belongings from the car, and the shop made it go away. I'm definitely more careful with my newer cars. My first car didn't burn oil, but dripped. I'd just top off the oil whenever I started hearing the tappets clicking. It was quite a forgiving engine, a 1975 Dodge.
