Ratteling Sound!!!!! 
JUST DROVE AROUND THE BLOCK AND I HAVE A SOUND COMING FROM THE FRONT OF THE MOTOR.....LIKE A LOOSE BALL ROLLING AROUND THE FRONT OF THE ENGINE.....TOOK OFF THE VALVE COVERS AND CHECKED ALL THE ROCKER ARMS....GOOD.....NOTHING IN THE TRANNY......SOUNDS LIKE ALLMOST AS FAR FORWARD AS THE TIMING CHAIN...BUT NO MISS OUT AND SPUTTERING OUT.....RUNS FINE....I ALSO VIEWED THE THREAD ABOUT THE COLLAPSED LS7 LIFTER.....THATS GOT ME WORRIED......MY SERVICE MANAGER SAYS SPUN BEARING.....OTHER GUY SAYS ROD????.....HELP ME OUT... How recent is the clutch? Does it do it when its warmed up? Or mostly when its cold?
Some of the newer Ram HD clutches have been making that exact noise you are describing. Some days, mine is pretty bad, others its not. Also depends how hard I have been on the clutch lately.

guys i have the same problem, i bought this car from a guy on this website and when i start the car you can here something rattle pretty bad in the front of the engine. once it is on you wont hear it anymore. any ideas what it can be. i've been trying to get a hold of the seller but he has not shown any interest in calling or e-mailing back. can someone help me?
If the noise increases as it warms up it is probably a spun connecting rod bearing, I am currently working on one with the same problem as you are describing, crank the car and unhook the coil packs one at a time, listen for the noise, if it quits then that is the problem cylinder. The metal in the oil is more then likely bearing material.
