Had a brief foray with a Ram 2500 that had the 6.4L V8 Gas engine. Loud engine tick at cold start and constant clatter at idle - the thing sounded like an ecodiesel. Dealership acknowledged there was something wrong, but could not determine what it was. Chrysler recommended to "tear into the engine to see what's wrong". Dealer refused to do any work until they knew what was wrong. Tried to convince me nothing was wrong with it. Never had an issue with my previous 2 Silverado 1/2 tons. Shame on me. Dumped the Ram, disclosed the sounds with the Chevy dealer, took a loss, and got the 3500 Duramax/Allison. Happy camper.
Here are some pictures. Had the running boards installed yesterday. Will get some more pictures up later.
