On my 2000 Hyundai Accent...lovely. I dont know what to do. My options, fix the timing belt and find out if the valves and pistons are bent, which is like 95% possible. Then after that the guy who will be fixing it said there could be thousands of dollars in repairs. Is there a way to find out if anything is bent before I fix the timing belt? What do u suggest? Sell the car completely? And about how much could I even get for it with a screwed up engine?
I ALSO heard that theres usually a lot of ruckus coming from the engine with all the valves and pistons colliding. The belt makes a loud snapping noise aswell? true? If so, when I was driving it lost power completely and rolled to a stop. I did not hear a thing! It just stalled, that is all. If that helps?

Re: Timing belt broken
This is an interference (valves hit the pistons) engine and will cause engine damage if the belt brakes, the best thing to do is put the belt on and see if it starts, I have seen some dodge the bullet on occasion. In most cases u will hear nothing, the engine will just stop running.

Hard to say. Depends on how fast the engine was running when it broke. Sounds like pretty fast from the belt getting mangled, right? You can put a new belt on and see if the engine will turn. If not, you know you've at least got some bent valves that are not seating. You can also loosen all of the rockers to see if that will let the engine turn--then you wouldn't have to buy a new belt before deciding whether or not to fix the motor.
The timing belt is inside the valve cover. You have to remove the the valve cover gasket. Underneath that you will find the valves, the head (the top of the engine block). There is a pulley that is used to tighten the timing belt. The pulley is attached to the piston and valve timing. This pulley is usually marked as to where it should be positioned in relationship the timing of the pistons and the cam shaft rotation. This is what is referred to as stting the timing in the engine, and the timing of the distributor. Since your belt is broken the engine has lost track of its timing, so you might have to refer to a manual on your model of car to set the timing. You will also need to replace the valve cover gasket when you put the valve cover back on.
If you have never done this kind of work before, buy an aftermarket service manual to guide you. Timing belts or chains improperly installed will cause rather expensive damage to an engine if, as most are, yours is an 'interference' engine, meaning that the valves and pistons can contact (and damage) each other if the cam timing is wrong.
Haynes or Chilton will have them available for your car and the $17-$30 is a good price for the amount of info you then will have.
Most all auto parts stores will have them available.
first thing i need to know is did the timing belt break? second is are you sure you aligned the timing marks and after the belt tensioner was tight you rechecked to make sure the timing stayed where you had it. next step would be a compression check to if a valve was bent whenchanging the belt i have seen this happen and this engine is an interferance engine. later paul
