Hi,
I have a 2013 1500 with a 5.7L hemi. I have had it since new, and have had it serviced at the dealer for the first 90,*** miles. I then started doing them myself and used Mobil 1 oil in it. I know Mobil doesn't meet the mopar spec, but it is a better oil than the lower end Mobil oil so I used Mobil 1 in the truck with OEM filter. Truck has 109,*** miles on it now, and the lifter ate the cam and it is now getting a new motor. I daily drove the truck and never knew about the cam issue.
I pulled the codes and knew it was toast after I saw the misfire codes and did some research on the internet. Truck had a valve spring failure that was covered by Chrysler at just over 60,000 but no other issues. It started up first time, every time and I could stomp on it and had tons of power...until I got the check engine light. At that point I took it to the dealers and they charged me $450 (CDN) for diagnosis and then told me that it wasn't worth doing a cam and lifters as there was likely metal throughout it. I probably should have done an oil analysis to see how bad it was, but I need the truck to drop off my kids etc so elected to go engine swap.
Dealer quoted me $9900 (all $ figures are CDN) for a used engine with 50,000 miles on it. New motor was $10k, but none in stock and $3k for labor. I had the truck towed to an engine shop who ironically has a cache of crate motors from Chrysler, so they are doing it for $7800. Loads of money, and I could do it myself, but without a covered space and the rain that we have right now, I couldn't do it in a reasonable amount of time so I am paying them.
Thinking now I will be going with oil analysis once in a while and perhaps just preventatively changing the lifters in the engine at around 75,000 miles. At least that way the repair is planned and not as expensive as a new motor. Never thought that the lifters would go, and am usually overkill on the mechanical stuff (I enjoy it as I am a mechanical engineer) but never expected this. This is my first Mopar and might be the last...
Might sound like a sob story, but it is what it is. Just want to share my experience so others don't suffer the same fate, I thought the rest of the truck would be failing before an engine. I would definitely consider doing oil analysis and perhaps preventatively doing the lifters. I haven't looked into how practical doing the lifters would be...
My friend had a 2010, his failed at 78000 miles.
