2013 5.7L Cam/Lifter issue

[kris72079]

A major contributor to lifter failure and subsequent cam damage on these hemi engines (as well as with other late model manufacturers) is the MDS system. Given that you are experiencing a misfire on cyl 4 (P0304) I'd suspect that you have a component in that system beginning to fail as it operates on cylinders 1, 2, 4, & 7 if memory serves. Could be as simple as a failing MDS solenoid, although that should trigger it's own DTC or a failing MDS lifter. You can attempt to prolong the inevitable by immediately manually deactivating your MDS everytime you get in the truck or purchase a programmer to turn it off. With either option you still carry the MDS components with you. A complete MDS delete is the only permanent guaranteed solution for it to remain trouble-free.

Thanks brother, I’ve actually been looking at a MDS delete kit from MMX. Probably going to go that route. I appreciate the info.

FCA is not the only one having issues with MDS. I don't know if its as bad but GM also has issues with this.

I was just talking to a buddy of mine yesterday about GM burning up pistons with their cylinder deactivation system . He's got a close friend who's a tech at a Chevy dealer and says they get one in on a weekly basis with issues similar to this or other issues caused by the cylinder deactivation system ....I believe he said it's mainly on the 5.3[emoji848]

GM has very similar issues with their DoD system as it is very similar in operation. It is mainly on the 5.3 because it is specific to the 5.3

As soon as I return from deployment I will be doing the MDS delete on mine as well using the MMX complete setup. My 2010 has just over 70k miles and has shown signs of issue since around 55k. I will be doing a complete write up on here, but that is still a few months off.

I don't know that I agree that MDS is the issue, if it was then only MDS cylinders would have this issue. My failure was on cylinder number 3, non-MDS cylinder. Based on pictures I see and what my lifter looks like it's a week point on these lifters, my guess is the bearing that the roller is on. Mine isn't the only one I've seen in posts online that had failures on non-MDS lifters.

The lifter part number has changed with Chrysler and the lifters are on back order which tells me they are redesigning them. The MDS delete kits I saw when looking for parts used the Hellcat lifters which have a much larger roller and bearing on the lifters. I could be wrong but with the general hate for MDS I see it would be easy for people to jump to that being the issue.

Wow. I'll take a cam/lifter replacement over burnt pistons any day...

There are other threads on this forum stating that its usually non MDS lifters failing.

Sorry I let this thread go dead for so long...I was on hiatus. Anyways, I’m back and still have the same issue. Truck starts, rough idles for a bit (30sec?) on cold start only, then runs really good virtually perfect....until the next cold start.

I’ve used my Diablosport T-1000 to clear the P0304 Cylinder 4 – Misfire Detected code....just to see if it comes back and it does.

I still think the P0304 relates to a faulty lifter, and may have begun wearing into the cam.

I’m in Texas, Dallas/Fort Worth area and I need to get this fixed. Dodge dealer and FCA were worthless on this issue...so. I’m looking for a good reputable business that I can take my truck to, have them troubleshoot then, fix.

I don’t have time/space/tools etc, to dig any further into the misfire/lifter issue myself, and I would like any business suggestions that I can get for places that are knowledgeable hemi engine experts in the DFW area and would work with a custom tuner. (If I must replace the cam, I’m going to upgrade and would want that paired with my existing bolt ons and custom tuned).

Thanks in advance!

not sure how far it is from you but Jay Greene is out in Mount Pleasant.

 

[crackerjack1957]

I would say 117 miles to Mt. Pleasant is worth the trip

Yeah I spoke with Jay, he doesn't do the installation anymore...just orders parts and does tuning via phone/email.

If my truck needs a cam, I will most likely go thru Jay for parts and custom tuning.

ah bummer. did he recommend someone atleast?

He had a guy about 30 miles from me, but I want a shop (company) that I could come back to if something doesn’t work.

Well for $$ sake, this is about the best that could happen.

I called a local shop here in the DFW area (shout out to Bevil Automotive in North Richland hills). The owner Craig Bevil, was pretty confident the issue wasn’t lifter/cam failure, but most likely an injector.

I swapped the injector ($60) and she runs like a top!!

I will be swinging by to bless Mr. Bevil (monetarily) for his keen insight. And he will get all of my business in the future!!

For all those having any issue...run all the traps, especially the cheap ones before accepting the doom and gloom!
