We have a 2012 ram 1500 sport with 160k miles. Reading over forums for a week has done nothing but confuse us. Engine is torn down, we can see pitting on 2 cam rollers and one lifter is deformed. I’m the wife and don’t know technical names, please be kind. I’m looking for advise on what we should do. We still owe on the truck and my husband would like to keep it. The vehicle has been properly maintained since we purchased it with an existing 40k.
