I can replace the lifters on mine if needed myself.But I admit I'm a little older and lazier to tackle it tho.Especially on a motor with this high mileage.I have done excellent maintenance on it for last 120k Ive owned it.Posted this in another similar thread. But it's good to see high mileage Rams still getting with it out there. My 2014 2500 Big Horn 5.7 has a bit over over 220k miles on it and still goin strong. I'll drive it until something breaks then fix it and keep goin.
