Any chance the noise might be caused by the timing chain? (I hope not!!)

It drove for like 3 weeks with that noise until the big break down happened... Since you are DIYing it, it is a good idea to change both belts there and all the pulleys. Some people recommend to change the water pump as well, but I did not change mine since it looked good to me.
