Had a Chrysler exec demo Ram 1500 with the 4.7 got rid of it at 90K miles when the lifters starting rattling at every stop light.After much research from mechanics at Dodge dealerships, I was told the oil passages and internal design of this engine was flawed from day one, but Auburn Hills decided not to drop production but let it fly. Kind of like built in failure engineering. Sell the vehicles, repair em' later...
