Every time I drive by exit 4 in MA on I95, I look over at the spot where my Mk2 diesel Golf caught fire because of a leaky ring. Depends where the leak in the gasket is. could have the same result. Someone correct me if I'm wrong.
So I'm driving down the road and fire blasts across my windshield. I managed to coast into a parking lot where I (think) I learned what a runaway diesel is. The motor ran as fast as it could until it burned through all the oil in the engine. There was a billow of black smoke 100 yards high. And the whole front caught on fire.
That was years ago, so I was still stupid enough to go back in the car to get something hidden under the back seat. Or be stuck with out anything to do for hours.
Anyway, I didn't have to call the tow truck. They could see my smoke signal.
