Try touching around the engine to help narrow it down by feel if you can but stay away from the belt so you don't get hurt. With something making that kind of noise it has to vibrate the hell out of what ever is making the noise.

^^

You can use a "slot" or regular screwdriver too, touch somewhere on the engine with it and put your ear to the handle. but yeah be careful man.

I had to do this too with a bad pulley wheel, but I used a piece of 1" conduit to set on bolt heads to locate the source. BE CAREFUL AS HELL if you're goin to do it.

your fan is fully electronic correct? If its not i had a noise like that but not as bad when my clutch for my fan had quit. Its an electronic clutch but the fan is driven by my water pump. It would make a sound like you are rattling the hell out of the fan shroud but mainly at 1500-2000 rpm's and then go away if i gave it more or less gas. I would just for the ease of it remove the belt and check all the pulleys on your car for any wobbling if you pull them up and down or side to side, if it moves a lot then the bearing on that pulley is shot and needs replacing. I dont think its the belt doing that or anything on that part of the system but you should really get that corrected before your belt shreds on you.

When this noise does your fan on the radiator spin any faster than it normally did? Maybe the fan is a little loose and it is spinning faster temporarily to cool off the system briefly and it is rocking the fans housing around? Idk without being there to hear it in person to trace its sound. If you rev up the speed on the engine does that sound get faster and louder? Does this happen when the engine is warmed up or even when its completely cold after sitting overnight? If it was a lifter you would not hear it going that fast for the knock and if they were coming into contact with your piston it would make a slight pinging noise from what i heard on my friends car. Please get back to me on that.
