i've been working on a pc controlled rc car with arduino
so it's almost done
i was testing it and having fun
but i noticed that the rear motor is not spinning forward anymore.
i also noticed l298 motor driver got very hot it was even hard to touch.
so what im asking is can it be possible that the part of l298 that runs motor1 forward might burnt and other parts of l298 inside stood still

Yes, quite possible.
The real question, though, is why did this happen? Did you measure the running and stall currents of the motor(s) being used in the car? Did they exceed (or come close to) the current capacity of the L298? Did you have a heatsink mounted on the L298?
I would go back and recheck your design - it may be that even with a proper design, the L298 is too small (in current switching capacity) of an h-bridge to use for this project...
ongoing development of the project is here

what motor driver do you suggest? for this project

Ok - first off, you already have a thread going for the project, and you are asking nearly the same question there; this is very close to "cross-posting" and is frowned upon here...
With that said, I (nor anyone else) can reccommend a motor driver without knowing the current limits (running and stall) of the motor to be driven. This information is important. If you don't know them, then it is time for you to break out your multimeter and find them out.
BTW - I replied in the other thread as well. Pick a thread topic and stick with it...
