I had an '82 Ford Escort. Those things were notorious for lunching the motor if the timing belt ever broke (which they did every 45,000 miles like clockwork) while you were traveling down the road. The valves would stop in whatever position they were in at that instant, and then the momentum of the car would keep the pistons moving up and down, bashing the piston tops in to whichever valves were unlucky enough to still be open, ruining pretty-much everything. At the same time I owned that car, my best friend owned an '82 Chevy Cavalier. We were constantly one-upping each other over who owned the biggest turd…
To be fair, that’s the expected outcome for any interference engine that loses the timing belt, which is almost all modern engines as far as I know. 45k is a really short lifespan for a timing belt though :/
actually now that I think back it was the water pump that regularly went out at 45k, and it was run by the timing belt. The noise coming from the water pump is what usually alerted me and I was able to replace it and the belt at the same time, which spared me from ever losing the motor. I drove that thing til it had over 160k on it, which was a lot for one of those…
