I have a 2002 Hyundai Sonata 4CL (interference engine) that broke down recently (no longer starting) and upon inspection, found out that the timing belt needed replaced. After taking the timing belt off, we found not only a lot missing teeth on the belt in general, but there is a large section that the teeth are all missing, which leads us to believe something may have jammed. Also, knowing that all of this happened while the car was in motion, the big concern is that the pistons may have been damaged. Right now, our option seems to be to replace the timing belt, put everything back together and cross our fingers that it will work. Or is there another option/way to make sure there wasn't engine damage? Please forgive me if any of this doesn't make sense, my boyfriend is the one working on the car and this is what I've been able to decipher.
