Hello all,long time lurker and finally decided to reach out in hopes of a solution I have a 2014 citadel 5.7 just did the ams mds delete kit with cam lifters new oil pump amd have this awful tick noise. Runs fantastic but jus has an awful noise, I have ran it with the valve covers off to verify oil flow and pressure to top end any insight from you more experienced Mopar owners would be much appreciated(tried to upload video site won't allow)

Welcome to DDN. You'll have to put the video on a host site like youtube, then post a link to it here.
Did you install OEM lifters. If not, that will be a good part if not all of your issue. A proper set will run you at least $900.
Lots and lots of fake crap out there these days. :0(

Bad lifter even though they are new. Seems it is not pumping up enough at idle so you get the clack. (i do not hear a tick, I hear clacking)
Does it go away with higher RPM or just speeds up with higher RPM?

Yeah, that's louder than a tick.
Have you contacted AMS? Did you buy the entire retrofit kit or just pieces?
When you had the valve covers off did you notice one pushrod pumping less oil than others?
Also, I used to soak my lifters over night in oil and even tranny fluid and prime them but not sure that is required on a Hemi?
As stated, some parts even new are defective. If you can narrow it down to which cylinder that might clicking that might be helped too. Try using a stethoscope or long screw driver and listen where the noise is coming from.

Sent video to ams the offered to sent me another set of lifters free of charge but would need to purchase everything else again...everything seems normal oil flow wise I had purchased the entire kit including the oil pump i had the lifters soaking probably i week while I did the job outside in my driveway a few hours a day in the mornings l. I drive it today hoping something would become more obvious it cruises smooth as can be 75 mph jus noise at stop lights
Don't soak the new lifters. Just apply some assembly lube on the outer surfaces. If you soak them, they're already full on first start. 3G hemi engines don't lubricate the way most pushrod engines do.
Double-check that you didn't bend a pushrod or something upon first start up.
I hope you're at least pulling the pan and cleaning everything out with a ton of something like kerosene. You don't need a "hellcat" pump, as these engines run on all 8 at idle, so they get full volume then. But, if there's any question of whether you should replace it, the regular Mopar or Sealed Power pump is fine. Melling if neither of those two are available. Same is true for the lifters and cam. Melling was the vendor until '22, then Sealed Power.
Although lifter quality is a factor in these failures, it's not the primary cause. 'd strongly consider running synthetic 0W-30 or 0W-40, but no additives. Use purple OAT, not Dexcool for the coolant. WIX/Puralator oil filter.
Another thing to keep in mind - compare the costs of doing all this vs a short block. Powertrain Products is the current vendor for Mopar remans (V6 and V8). You can go right to their website and get a price directly from them, and cut out the middle guy (Mopar) for a lot less.

I did go with a meiling pump,pushrods seem to be ok but thats my next step is to pull and measure them appears to be driver side my hope is that's all it is.this is the second time this thing has been apart had the heads decked .008 and new headgaskets installed with oem mds lifters,200 miles later the new Mopar lifters failed and ate the camshaft which prompted this delete kit,
You need to check the pushrods for length and straightness, you could have an issue there (tolerance stack up).
I hope other readers see this and learn that deleting MDS is absolutely not the solution to hemi lifter/camshaft failures.
If you milled the heads and didn't check pushrod length, shame on you.

Ok on the video. As others have commented, that noise is not right. Who is the AMS folks are mentioning?
I want to focus in on a comment you made in your post #10. You said that you had installed another set of lifters? These were supposedly oem MDS lifters? Do you still have them, and if so post pics please? If they were aftermarket or fake crap, that's why you are where you are at present.
Not trying to be critical, it's just that the more background we know/understand, the better chance we have of helping you find success.

trust me I know i should of slowed down a bit figured .008 off the deck would of been fine but seems it was enough to bend an exhaust push rod
They weren't lying. The "bad run" started in 2005, and it's about to resume shortly, as they aren't making any changes to new hemi assemblies for 2026+. It doesn't surprise me that they won't stand behind the parts, either.
I'd seriously consider, at this point, getting a hold of PP and seeing what they can do for you in a short block. The amount of metal you've got going through your lube oil system will trash your rods and mains in very short order.
A good used engine will cost about the same, or more. Powertrain is actually offering a much better warranty directly from them, than Chrysler does for the same exact product that Powertrain builds for them. Not kidding.
Here is a possible solution to your lifter issue...
A little pricey:
Johnson 2326R Hemi Gen3 Drop-In Lifters for 2003-newer Dodge Chrysler Jeep Hemi Engines 2326 non-MDS Lifter 5.7L 6.1L 6.2L 6.4L - Michigan Motorsports

Those might be ok on a brand new engine or in a reman, but he's on his third try at this. The engine has to come apart and get hot-tanked or replaced. The lifters are a symptom, not a cause.
