Just bought a new 06 ram 4x4 with the 4.7 and have noticed a few noises and I'm not sure if its normal or not! First off, there is a slight constant ticking noise that comes from both sides of the engine, second it sounds like something is rattling around in the engine (its not loud but I notice it) I crawled up under the truck and can hear it better from under the engine...and lastly if I'm sitting still every 5-10 seconds the truck will have a slight vibration that moves throughout the cab and I called the dealership and they said that the 4.7 has a slight lope that will cause this vibration every so often. Thanks
