Hi. I had the same thing (cold start noise) with my 2020. AND, I was doing the same thing with MDS - I just hate the sound, etc. BUT, and a big BUT here ... what I found is that if I drive for at least 10 minutes and let the darn truck turn on MDS for a few of those 10 minutes, the next start is QUIET, TICKLESS, MUSIC to my ears! I've been doing this now for two months and can go as long as 4 days in between starts with NO startup tick. Prior (when I was disabling MDS - just like you), anytime I let the truck sit for 24 hours or so, I'd have a few seconds of ticking. You should give it a shot. Just put up with the vacuum cleaner nosie, and let it go into MDS as often as possible, and see what it does for you. I hated the noise so much that I was thinking about selling it. Now I love my truck. I'll look forward to hearing from you.I have a 2019 5th gen, I always run with MDS disabled (gear limiter), its the first thing I do after getting into drive. I may have driven about 2 hours total with MDS active so far on the entire life of the engine and I'm at 50,000 KM's right now.

5.7 HEMI Lifter Failure Could this FIX the lifter issue FOREVER?
Hey guys, revisiting the 5.7 HEMI lifter failure video I made a couple months ago. I wanted to address many off the comments that I got from the last video, ...youtu.be
That video right there is why I turned on MDS again. I want pressurized oil getting to all my lifters at least some of the time…
Thats very true lol.Turn it back off
If you can run your engine for 5 hours straight with MDS turned off, and have no lifter failures, I GUARANTEE you that oil is getting to those lifters in sufficent quantity. It's basic logic, without proper oiling you're going to lose your lifters far quicker than that.
Any of you guys every try to operate a drill press without oil/lube? A few seconds without oil there and you'll understand why we can be guaranteed that "lack of lubrication" is NOT the hemi's problem.
It's not cam hardening, or should I say lack of, you can't even think that is it when we have hemi tick as part of the deal. Obviously, there is an issue with the side force on lifters, this is the problem, it explains everything. It explains why EP additives have been proven to be effective (those only work on perpendicular force), it explains why the scuffing on lifter bore, it explains why the cam lobs are worn over time, it explains why needle bearings fail, it explains why they tick, and it explains why only some cam lobs are wiped. It is so easy to disprove the cam hardening theory it is hard to take serious.
It is not lack of lubrication per say, it is poorly formulated oils and a poorly designed lifter action. When you have banging metal, oil will not be enough, base oil will just be squeezed out.
