Having a membership in the 5.7L lifter issue club, I thought I would post this video that I came across for those who have experienced this issue, for those who want to avoid it, and for general knowledge. Enjoy.
I had my failure about 3 years ago at 105k miles. My first warning was a code for a misfire on #5. I repaired it with MSD delete and added a mild cam with a tune. Since then it has been running great.@work and cannot view all of the video but if he is blaming MDS forget it. The lifter roller failure is not because of MDS.
Its like a bad lottery, I just did a prevention lifters swap keeping MDS. Changed lifters, springs, stem seals, and pushrods @135k miles. They all looked great but I plan on keeping the car.
I do have a blower and MDS disabled and shift @6k rpms at play, before and after the refresh.
I used MOPAR lifters dated 2020 on the packaging.
What are your symptoms?
The lifter issues are pretty common on the 5.7 It can happen on 6.4s but not as often. But Dodge is not the only one, started much earlier with Chevy LS engines and still going.I’m just going through all of these, since this is the prob the strangest car I actually worked on - how common is this? My RT has 118k & was maintained ok at best
