My brother just spent $15k on a new engine and transmission for his 2013 Ram 1500 at 305k miles. The lifters and camshaft stated ticking at 275k miles. It's still a nice truck and was going to be $55k to buy a new one.
He got some pretty good life out of that engine. I met a guy last year in SC that had a ram 1500 with a serious tick. It had I believe 80K on it and he was worried. I asked him if he idled the engine excessively, he said No. He drove highway and changed the oil every 10k with mobil 1. O think that is the problem. I would go 5k on an oil change and screw what the manufacturers say.
