Thanks for the advice. I don't think it's an exhaust leak. The sound is definitely coming from the engine, not the exhaust. Also, any idea how much replacing them would cost (if it is the lifters)? And is it necessary to change all of them at once?
Also, Dodgeram07, is that a smart car I see in the bed of your truck?
