ok i just recently changed my timing belt on my d16y8 and after installing everything it seems like the belt is loose... i mean its not loose that it will fall off but if you wanted to make it slip off it would with a little jerk... i did all the process correct, or maybe not, but the car starts and everything, its just that its kinda loose and i can hear the belt slaping the timing belt cover when i rev it up to 2500 rpm... any help or maybe give me the procedure for putting it on or something to check if its the same wat i put it on or same steps, thanks...
