Sounds a little scary. Do you recall where, front or back, driver's or passenger side of the engine the noise was coming from? Did it seem to get louder and clunkier as the engine slowed, seeming to be tied to engine speed?

These things can be hard to understand when you are there, in person, and from the other side of an internet connection it is even more difficult.

I agree with jbaj007 that it sounds like an accessory drive from your description, than an internal engine issue. Did you check the single, serpentine drive belt and the pulleys it is wound around? If one has come loose or the bearings are shot, it might make a clunking noise.

Good luck, Jim
