No. Not the first time I have heard that either...

 

Any ideas

Hopefully a fluke and replace with stock

 

Tell your friend to try using Seafoam.

I do recall someone (I'll research) aftermarket making lifters, but many stockers living looooong lives on some high HP builds.

ETA:

Coming soon... Johnson Lifters & Arrington Performance are bringing out a new high performance lifter for the Gen III HEMI! Available exclusively through Arrington Performance, these new high performance lifters will be drop-in stock replacements for the 6.4L HEMI!

:Here is the deal. We build alot of Hemis and contrary to popular belief we do invest more money into R&D than anyone wants to give us credit for. The factory lifter does a great job. Building quite a few very high rpm and testing some more agressive cam grinds in our current hemis with better spring packages shows the stock lifters lack the stability necessary to keep them from collapsing. Those who Actually assemble and do alot of work checking Piston to Valve clearance know that on some cams we get away with less than .020 thousands clearance. How does this happen?? Because Dynamically the lifter collapses every time it moves. These lifters are designed to resolve that issue. They are not intended to work with MDS this is a Performance lifter for those who want maximum performance. The lifter does not rely on top fed oil making an entire new arena of flexability in rocker arm design possible. The Jessel conversion is over 10,000 dollars all in and in a few cases so much machineing is required the cylinder heads crack because not enough matierial is left for support. We are commited to bringing useable quality parts to the market. Someome leaked the lifers so we fugured we would introduce them. We are in the process of prepareing for some very heavy spintron testing. 440 3.0 is just around the corner

Thanks

can you explain please?

 

Not much to explain, go to store, buy Seafoam, use as directed. Pour it in the crankcase (where you put the oil in) run it with current oil for a few 100 miles or so prior to an oil change. If the lifters are sticking because of bad maintenance practices or neglect, this may help the issue.

Long story short....Bought a car for my daughter, 90 yo lady owned from new, 2 years put all of 30k on it and then it sat for around 4 years. Got it cheap, got it to crank and had bad bad lifter tap. Pulled the top end down, soaked in Seafoam, put it back together, cranked and after few min of run time, it quieted down to sewing machine status.

well my 2013 only has 9k miles and i am also getting noisy lifters on the left side..and my maintnence is fresh mobil1 0-40 and filter at 3k...

 

MDS lifters are noisy in general, especially on an aggressive cam and springs. What it really comes down to is how noisy are they?

 

on mine it was noisy enough that when i had the windows down at a stop my friend asked me wth was ticking in my car

 

yup, it's that double plunger. Ask the 5.7 guys how loud their cars get with big cams and retaining MDS lifters.

 

stock cam in this car -_-

 

you ever see the specs for a 6.4 SRT cam? Trust me it qualifies with MDS.

 

So just because there noisy doesn't mean there bad? My challenger lifters are noisy also more so when it gets closer to a oil change

 

would you guy recommend a oil treatment like BG RF-7? They have "said" it quiets lifters. I dunno never tried it in my SRT

 

I ended up replacing MDS Lifters and putting in new non-MDS Lifters on my 392 Cam swap. Those things are junk.

There is a star service bulletin out for this, and I'm hopefully going to get it done in the next month. My lifters clatter on cold starts sometimes too. I never have an unusual tick when the engine is running or at temperature idling though. My old 6.1 never did either. My old 6.1 did clatter at startup occasionally just like my 392 does now though. Apparently there is a little tab on the back of the lifter that can get bent on installation causing oil pressure to leak down and you get the ticking noise. Lots of talk about it on the Challenger forum. This was new info to me as of a couple weeks ago and I was glad to see it

Here are the last 3 pages of the Star bulletin... Hemi Tick or No Hemi Tick --- there IS a problem with some of the engines that are ticking. If your dealer/service tech won't research this for you, hand them this!

so if its ticking bad, they have to replace the lifters free? cuz theres been some times its ticking bad enough to scare me

 

I haven't read all the way through the service bulletin, but I think they adjust a tab on the lifter that prevents pressure bleed down.

Best to get your tick on record with your dealer and express your concern and also that you would like this service performed. They shouldn't resist you from getting warranty work done.

 

basically there was a false torq reading upon assembly so the push rods were acting like they were too short

 

The warranty is gone and im mixed up with opinions

this is the third time i change lifters

should i go aftermarket? Or 6.1 lifters?

 

Who makes after market lifters? Fyi 6.1/6.4 same lifter

Wow. Its been about a year since ive heard about those. Are they even up for sale yet?

Do you know of anyone using them?? The pic is for a gm im pretty sure. No mds if they are even out yet or if ever . Lots of big power cars use the stockers so im comfortable using stock. Besides the tsb doesn't even show its an actual lifter is its a rocker shaft install issue

Ok ok i will install 6.1 lifters this time
