When im driving its making a rattling noise it does it when its idling to just not as loud when I reach 4000 rpms it goes away and my gas milige has gotten worse none of the warning lights are on in the dash and when you do a systems check everything comes back good transmission seems to be shifting fine I thought it was a pully but I took it to get checked out and I was told it was the valves but I dont think it is because the rattle would never go away it would be constant

IT could be the valves. At a higher RPM the oil pressure may be getting high enough to stop the noise.
