Been awhile since I’ve posted on here. Well I’m having a lifter tuck now at 101k miles. After searching for forever, I’d like to just stay a stock 5.7 cam but do a MDS delete with Hellcat lifters. Now I’m concerned about can a guy run the full 16 HC lifters on a MDS cam without wiping the cam after start up? Can’t find any info to back up my thoughts. Maybe somebody else has the info I’m looking for.

Hey man, we ended up with the same fate. I haven't been around as much either but got a stuck lifter on #3 2 weeks ago at 138k miles and it wiped the cam. You are but one more case in a very serious problem with the lifters on the 5.7 around 100k miles.
I should be picking my truck up tomm. I ended up getting the whole stage 2 cam kit from Moe's and replacing all the lifters non MDS....it's tuned out already and have an updated tune to load for the cam.
I'm not sure on your specific question though. You can disable MDS thru tune or ditch the solenoids and put delete plugs back in.
I'd be more concerned if the stuck lifter has already started eating a lobe on the cam. You may need to replace it all.
I've just put $3k in parts and $1500 in labor to fix all this. Have you checked your oil/filter for metal?
My truck threw a simple #3 misfire and within 1000 miles it was bad metal on metal and had to have it towed. We found the lobe on #1 was also starting to get eaten. Totally insane...notify FCA even if you don't take it to a dealer. They track every reported case but if it's only done thru third party mechanic it never gets logged for possible action/recall. You aren't alone.....it's becoming an almost daily occurrence to see someone post about it.
