6.4 Hemi MDS delete experts?

[DirtRoads]

I have a 2016 Ram with about 110k on it that has been bulletproof until yesterday. She sat for about 2 weeks and acquired a constant lifter tick when I finally cranked it up yesterday. It would occasionally tick a couple of times if it sat for a few days, but now it won't go away

So, MDS delete. Yay.

I'm looking for the highest quality and most complete kit available. Install seems straightforward enough IMO. I'm going to call around and get more info about these kits, but I'm really wanting to hear some first hand experience.



A friend recommended AMS racing that comes with a PCM exchange and a handheld to make the technology happy.

Then there is Texas Speed Performance. Parts only, Id have to have the PCM unlocked and find a way to tune it. There's a local option for that, I believe its ~$500ish

FRP Tuning has a whole kit with tuning through HP tuners.


Please share your experience, if you have any. Some suggestions that I have already received are marvel mystery oil and a for sale sign, LS Swap, and a supercharger while I'm in there. I think I'm just going to stick with the lifters and cam for now

No expert here, but from my understanding it could also be the exhaust manifold. Have you verified where the "tick" is coming from?

It’s pretty clearly mechanical and not exhaust. Very metallic, unlike any exhaust leak I’ve ever heard. More of a clack than a tick.

I talked to AMS today. The tuning actually goes through Diablo Sport. I’m leaning that direction

All I can say at this point is may your diagnosis be correct. Good luck...

I hate the 6.4.

"Lifetime" warranty until it seized with 36K. Then it was commercial use and warranty denied.

Well..I’ve got one. It’s been good to me so far.

I have ran it 4 times for about a minute each since the initial “oh shit” run. It has gotten to where the lifter will prime up within a few seconds of starting, but it makes the noise every single start. I shot a video to post, but I guess it’s too big to upload. It’s definitely not an exhaust leak.

You might be able to hear it here if this link works.
