5.7L Hemi MDS deleted, non Mds cam shaft, Hell cat oil pump, Hell cat lifters, DiabloSport I3 Tuner
So I’ve searched through a lot of threads and can’t seem to find any information on my particular issue. I have a ‘14 Ram sport crew with the 5.7L and 8spd and 187,000km. I did the cam,lifters and mds delete in it at around 160,000Km. At the time I could not get mopar oem parts so I went with a jobber cam and lifters. Around 15,000Km later the tick returned. I figured that my jobber parts came back to bite me in the butt. I ordered new “hell cat” lifters, the hell cat oil pump and the non mds cam out of 2500. Upon doing the swap again I couldn’t find any obvious failure of the jobber parts that would cause this tick to return. I installed the all new Mopar Oem parts and hoped for the best. So now I still have the tick however it doesn’t tick at all on a dead cold start up. It runs absolutely smooth and quiet as butter until around 5-7 mins as engine warms up and comes to temp the ticking comes back. First thing I did was check all exhaust manifold bolts and found them to be good. Then I switched to the redline oil with the lube guard biotech additive. I now have around 3,000km on the oil and additive change and their has been no change, I actually think it’s getting worse. The Tick is quite loud coming from passenger side towards rear of engine and also a slight tick on drivers side rear engine. It definitely sounds like valve train noise but I’m at a loss with this thing it has nearly drove me nuts. Under the hood it runs smooth and quiet, under the fender wells it sounds like a sewing machine on a sheet of tin. Tick increases and decreases with the throttle and like I said earlier gets worse as engine comes up to temp. If anyone has any insight on this I would greatly appreciate it. Thanks!

Why on earth would you put a 6.2 high output oil pump in a 5.7 with VERY different bearing tolerances? because some moron on youtube said you should?

You didn't learn you lesson from using crap parts? (I have never seen any shortage of oem parts). Now you want to use parts that aren't designed for your engine?

did you replace push rods? was there a "failure"? or you preemptively swapped the lifters?

You guys with hellcat pumps will be blowing out seals, and having bearing failures... going to be an expensive mistake.

Melling makes 3 different oil pumps for the 5.7 aftermarket... with changable springs... You will also notice they didnt go super high oil pressure like the hellcat pump.

They DONT warranty the highest pressure oil pump because in high rpm it could be questionablethe (hellcat is even higher)... at high rpm 5.7 with a hellcat I am 99.9% sure it will starve the bearings.. bye bye engine. OH and blow out gaskets

okay well one your statement that "the lifter roller bearing problem can be mitigated by a larger volume pump" is completely wrong...

If you worried about that, I wouldn't reuse lifters from your old engine. Get new ones, remove MDS(yes even non mds can get hit, i know that!)... The bankruptcy lifters had quality issues. MDS can also aggravate the issue (when it starts to go wonky). Use mopar lifters and recommended oil...

Low oil pressure is a whole different beast. Why would you have low oil pressure out the gate?

read poll results, 80% chance at killing tick or making it better.

However, it might not work in your case as you deleted mds, as in mds actually lubricates lifters better then delete. I'm not a fan of mds, but it was never an issue with hemi tick or cam fails. The issue is not getting enough oil in the lifter bore, so you need an oil that can compensate for that lower oil flow. An oil with additives designed for that with heavy aw/ep additives and base oils. You wont find this feature in most oils, only a few have it, of which redline has the best distribution and brand name.

From my understanding of doing the mds delete on a mds engine IMPROVES lubrication vs the MDS setup.
The mds block off plugs act essentially as if the mds is always on (discussed this in my failed lifter thread) providing pressurized oil to the lifter galley always, and just the lifter is not mds so there’s no pin to hold open just a greater flow of oil.

top one mds lifter, bottom one non mds lifter. 12-15 minute mark this video... 16.45 mark he explains the lifter posted above.

His theory, if we could be in mds mode 24/7, there would me no lifter failure, note the beginning of the video for his credentials. Even if we have non mds lifters, tune mds on to operate all the time = no more cam fails? to be honest, above my pay grade stuff there, but it makes sense to me.

I think it was @Hemi395 that noticed reduced lifter ticking leaving MDS on?

Then we all thought about this, and understood this opens the solenoid valves allowing engine oil to the MDS lifter bores.

But - I recall reading that non-MDS lifters do not get solenoid valves, but I presume they would still share the same horizontal oil galley the MDS lifters have, which would mean they should be lubricated full time.

But, but - I also read both MDS and non-MDS lifters fail?

Not sure what you’re referencing in the video.

When the mds solenoid are installed they block an otherwise open passageway in the block and act like a valve opening and closing that passageway to the lifter galley.

With the mds block off plugs are installed, that passageway isn’t block and oil is always free to flow.

So doing the mds delete plugs with non mds lifters, you have an open flowing passageway leading to lifters without mds resulting in increased lubrication vs an mds engine.

in mds mode the oil is pressurized which is the difference. Putting pressurized oil right in the lifter bore, much different then oil pressure from on oil pump. Obviously both mds or non mds have cam fails and this is just a theory.

Watch to the very end. I had the exact same reaction to this video the first time I watched it. Its literally like the last 20 seconds.Wild one pointed it out to me.

At the end of the Vid He updates what he said verbally. Check out Page 19 of my thread; several of us discuss it and I have pictures comparing the functionality of the solenoid to the block off plugs.

Didn’t read read all the answers, so sorry if this has been posted. You can read the synthetic oil thread or just try redline 5/30 and royal purple oil filter. Many folks have eliminated the tick with this strategy. Good luck.

The MDS plugs virtually copy cat the engine being in full time MDS mode Mike.They supply constant oil pressure to all the lifters all the time. Fast forward the video to about the 24:30 minute mark Mike,and he explains the plugs a bit better. I've been running the billet Stanke block off plugs for about a 1/2 dozen years,and they work good,buy either the Mopar or Stanke billet plugs,don't buy the cheapy Chinese knock off plugs,as they've been known to give issues
