ticking noise after timing belt change.

well my belt snapped,changed it out redid timing truck started.drove down the street back up and parked.now toay i started it and theres a loud ticking noise coming from the front of the engine.its not the lifters/rocker assembly.i took the top plastic timing cover off,nothing is grabbing but i notice on the cam sprocket the belt is sitting towards the engine so the front of the sprocket has a good half inch of belt space.cant pinpoint it,my crank pulley is still tight but not torqued after install.any idea?noise will not go away after a while,i dont wanna cance driving it if itll damage whatever it is is binding or stuck.

the engine fan was the problem,had loose bolts.
