I need to know what is wrong with my timing belt, well actually it doesnt seem like the car is running weird in any way but the timing belt looks visibly loose. Its kinda scary cuz the timing belt covers are gone so im just hoping there isnt a possibility of the belt slipping off. Is it the tensioner? Need different belt? Something else? I dont know what belt that is (ls,gsr etc) because I wasnt the one who built the motor.

Can you guys help me out, is it a problem?
