Get under the car and stick a jack handle or something of the sort between the crossmember and the engine and check for movement on either side. Sometimes the bolts can come loose, or if the mount(s) are stuffed the horrible noise might be the fan hitting the shroud when the engine lifts up. If a mount is broken it is usually the passenger side that goes.
