I just bought a 99 accord v6 with 78xxx miles on it and when i start it i can hear a rattling noise. It sounds almost like theres no oil in the engine, but i just changed the oil last week, and the dipstick is fine when i check it. When i listen to the area where the belt pulleys are is when the noise seems to get the loudest. Any help/ideas would be greatly appreciated!

 

nobody knows what this could be?
