vI heard the knock from the front porch before the truck even turned into the driveway.
It was a deep, heavy clatter coming from under the hood, like somebody beating a pipe with a hammer. Every time the engine turned over, it knocked. Knock. Knock. Knock.
I set down my coffee cup. My stomach dropped.
I’ve been a diesel mechanic for twenty-eight years. I’ve heard that sound a thousand times. It’s the sound of a spun rod bearing, an engine eating itself from the inside.
My mother’s 1966 Ford F-100 came limping up the gravel drive, red and white, with my nephew Trace behind the wheel. He pulled it up beside the porch, shut it off, and the knocking stopped. In the silence, I could smell hot oil.
Trace climbed out. He’s twenty-two, tall and skinny, with a backward cap and a racing team T-shirt from a dirt track in Hastings.
“Hey, Aunt Nora,” he said. “Grandma’s truck’s making a noise.”
“I heard it from the porch,” I said. “What did you do to it?”
He shrugged. “Nothing. It just started knocking on the way back.”
“On the way back from where?”
He looked at his shoes. “Just driving around.”
I walked over and put my hand on the hood. It was hot enough to fry an egg. I pulled the dipstick. The oil came out black and thin, and down at the bottom of the stick, glittering in the September sunlight, were tiny flecks of metal.
That was bearing material. Copper and lead, ground off and floating in the oil.
“Trace,” I said. “How fast were you going?”
“Not that fast.”
“How fast?”
He wouldn’t look at me.
