So, folks, this is what happens when an interference motor loses valve timing...
where are the other 6 valves, you ask? sitting on top of the pistons, of course!
Yes, it was my fault. (partly) Yes, it was at work. And, yes, I still have a job.
Luckily, it wasn't a customer car, but one of the rentals in our fleet. It was a 2000 Hyundai Sonata. I had replaced the timing belts, and was most of the way through putting it back together. The boss came over and said to stop there, and start it up, just to make sure everything was all set before we put the entire thing back together. Well, what he didn't notice, and I didn't really know (first timing belt I've really done...) was that the crank pulley center bolt was not installed. The bolts that bolt it to the sprocket were in, but that wasn't. So, I started it up, it ran for almost 10 seconds, then one of the worst sounds you you could expect came from the engine. I instantly shut it off (way too late at this point) We put it back up in the air to see what happened. The crank sprocket had worked it's way off the crank, so the crank was spinning, but the timing belt, and therefore the cams, weren't. If the stupid keyway on the crankshaft had gone all the way to the end, we would have been ok, maybe just lost the belt. But the sprocket only moved about half an inch off the shaft, and just stopped spinning.
So, now I am going in on Saturdays, without pay, to work on it. (yes, he still wants me working on the car...) He wants to try to avoid replacing the entire engine if possible, so next Saturday, I will probably be pulling pistons, if I can. Three of them are ok, but #4 got completely ****ed. Like he's been telling me all along..."This will be a learning experience."
