One problem related to engine clicking and tapping noises has been reported for the 2003 Dodge Ram 1500. The most recently reported issues are listed below.
Driving down I-94 on 01/24/2006 from work going 70 mph and oil gauge bottomed out, and I had a ticking noise. Pulled off the highway and had truck towed to the dealership. Was told the engine was shot due to sludge. I maintained a excellent 3000 mile oil change. Currently, the truck sits at the dealership and I owe $27000 on something I could not drive. Help!!.
