Check the posts and reports. There clearly are sideways lifters that wiped the cams. I am paraphrasing what others reported on this site. I did not report it.
I have a 2014 Ram 1500 5.7 Hemi 101000 Miles on it last week my lifter Collapse in number 5 cylinder. I just ordered parts to rebuild the top end going to set me back a grand. I think ram needs to acknowledge they are putting cheap bearing lifters in their trucks Thousands of rams are failing. Good thing I kept my spare GMC Sierra 5.3 it has 300000 miles on it and still going strong why did I buy a ram? I must have been stupidAnother commonality that I've seen is that they all seem to be happening on cylinder #5 too. I thought maybe an oiling problem. I use Castrol synthetic 5w20.
I had been noticing a decrease in performance and mpg's over the last couple months on mine. Then one day I got on it pretty hard and that is when it really started showing problems and throwing codes. I've been driving it the past week, and as long as I keep it under 3k rpm I have no issues.
I got two bids of $3890 and $3350 to replace the cam and all of the lifters, so I'm probably going to go ahead and get it fixed this next week. Just trying to figure out if I can go ahead and step up to a 6.4 cam or not. I HATE spending that much money without upgrading it in the process.
Although I'm not a fan of the MDS system, I don't believe our lifter issues stem from it. The 2500 trucks have lifter failure as well and they don't have MDS. It was simply a bad batch of lifters from a bad supplier. I've seen a few videos of concern regarding oil supply/return galleys in the block but I'm not as inclined to believe that's a major problem as long as the proper oil is used.I heard recently they did acknowledge their lifter supplier issues they have been having for too long. It does strike a very small percentage of hemis... but obviously when it does it sucks. Fortunately you can do the work... others are hosed but they try to handle, have you talked to the dealer? This also is exacerbated by MDS and dirty oil. You have to be very careful with MDS and oil changes. I think if you can prove you did oil maintenance they are more apt to cover.
Everyone on the web always says "oh i changed oil religiously!"... sure you can say that but I think i did also, then i remember I often let it go 5k...6k... at times..
I read that if your MDS system gets clogged it can trash the lifters when its not activating/de-activing correctly. Chevy also has a lot of problems but theirs is a little safer since its not computer controlled(its oil pressure based)
Alright, last update was 20 July, here is another update; 21 more trucks in the past 8 months:
Previous update was:
This includes trucks whose owners said it was a confirmed cam/lifter failure, and does not include those who posted that they had a misfire but did not confirm it was a cam/lifter issue. This also only includes reports from owners here and not people who heard from their buddies' mechanic, etc... or whatever. Pulling data from other sites as well can result in double counting if a person reports it on both sites whether they have the same username or not, so I don't include those either. Lastly, this doesn't include those that posted that their Hemi was making some sort of noise but had neither misfired nor had any sort of teardown done to suggest that there was any sort of valvetrain failure.
I have a 2500 and have MDS. 2017 model 6.4L HEMIAlthough I'm not a fan of the MDS system, I don't believe our lifter issues stem from it.
