Yours must be an older model V6 if the engine has a timing belt, or perhaps a newer 4 cylinder Sonata. Either way, this is a bad situation that can only be avoided by proper maintence. I think all Hyundai engines are interference engines, the valves extend far enough into the combustion chamber to physically collide with the piston unless they close before the piston reaches the top of it's stroke. Normally, the timing belt prevents this collision from happening. If the belt breaks while the engine is running, belt valves and dented pistons are the best case scenario. More often, valves are bent and the top of the piston is punctured. Worse case is a cracked head casting that has to be totally replaced. I think the timing belts on a Hyundai engine are suppose to be replaced every 60,000 miles. I doubt you have a ruptured block, but you likely have a cracked head (hence oil in the coolant) which is expensive enough to replace. I feel your pain. I've lived this experience with a V6 Nissan I bought used with 100K that had not had the belt replaced at the 70K mark as promised by the former owner. I now have a newer Sonata with a V6 engine that has a timing chain rather than a belt, but my warrenty specifically states that the 10 year/100,000 mile power train warrenty does not cover routine maintence items, e.g. bascally anything made of rubber. It also doesn't cover the O2 sensor, which also is listed as a routine maintence item (but is covered by a seperate Federally mandated 80K emissions warrenty). If your Sonata has more than 60K on the odometer and the belt was never replaced, I personally doubt the power train warrenty would cover the damage. If under 60K, I would think the bumper-to-bumper warrenty would cover it. Unfortunately, it sometimes takes legal representation to get that point across (and I'm not a lawyer). More pragmatically, I would say you need to judge the potential resale value of the car vs the cost of getting it running again.
