Tough to tell without hearing it, but the valbe springs are easy enough to check. It only takes about a half hour to pull the valve covers, a broken spring will be obvious. If you need help with it I may be able to make myself available some night if it is soon. I can get the covers off in about 15 minutes now (got it down to a science!) Is the noise a grinding noise or a rattle? If is is in the valve train it should be obvious from under the hood. Does it change with RPM? Vehicle speed? if it changes with RPM with the car in neutral it is the engine. Try driving the car, put it in neutral and see if it changes fast with the drop in RPM or slowly with the decrease in speed. From there I can steer you a little better. Is the car an M6 or A4?
