2011 Inaugural SRT8 - 6.4L Lifter Bearings Bad

I received some bad news today from the dealership. I started hearing a squealing belt sound when I first start the car and it goes away after about 5 minutes. I took it into the dealer and they say it's an issue with Lifter bearings. They said I have to have the engine fixed or replaced at a cost of about $6,000. The car has 87K miles and I've always replaced the oil with Penzoil 0-40 after about 7 to 10K miles.

Can it be fixed by replacing cam and lifters? Or will there likely be more problems on the horizon?

Should the entire engine be replaced?

Should I trade it in for a new one?

I'm not so sure about Dodge anymore, this is very unsettling.....

Who around Jacksonville, Florida besides the dealer can do this kind of work on a 6.4 392?

A second opinion never hurts, especially with a potential major issue like this.

I don't know how good your dealer or tech is, but several things need to be looked at to determine what damage has been done, and options that can be taken for a good repair.

Best of luck and keep us posted.

Your oil changes should be 6K max intervals on the 6.4

Personally I would NOT just swap out the cam and lifters. Once there is metal throughout the engine from a failed component there is usually damage throughout the engine from the metal shavings circulating through the oil. If they will install a new one for 6k that is a good deal. That is if they will let you have your old one. You could then sell the parts off of your existing and recoup some of the funds. That is if you are in a position to be able to strip the old engine down... Just a thought anyway. Either way I would go new or total rebuild.

McCloud, if it's determined that there is major lifter/cam lobe damage, I would tend to agree with Stinger.

If you really love this car, and plan on keeping it, I would highly consider a factory crate motor..

Easy in/out swap with some warranty on the crate unit.

Something doesn't sound right here, either its how it you are explaining or how they explained it to you, but my spidey sense is saying you need to go get a second opinion. Lifters don't make a squealing sound....PERIOD.


Go get a second opinion for another dealership or reputable repair shop.


Just my two cents....
Good luck.

sounds odd as well for a failed lifter symptoms. your gripe does sound like a suspect AC compressor clutch or something along the lines of something in the accessory drive/pulley/belt.


is your car an automatic? if so the MDS lifters are a known problem especially past 80k miles, read here:


https://www.challengertalk.com/forum...er-cam-652290/


If there is bearing failure somewhere in the engine, DO NOT just change the lifters and cam or you will be doing this again in short time. At a minimum the engine needs to be tore down to the bare block and hot tanked to remove all the debris. The crankshaft needs hot tanked/polishing, definitely need to inspect the cam, along with replacing all bearings, lifters, and the oil pump needs to be replaced as well.

"...I've always replaced the oil with Penzoil 0-40 after about 7 to 10K miles."


Are you kidding or what? 6,000 mile interval is the absolute max for oil change with synthetic. I never go more than 3,000 miles with conventional. You need to change the oil more often, as Hal said. That's issue one here.

We have almost identical problem, My 2012 SRT8 392 M6 is in dealership now, engine make some light knock noise, then I took it to the dealership, then I been told I need new cam and lifter, my car has 88k mile, and did oil change every 3500 miles, and this happen, luckily the warranty company finally covered this, or I need to pay $4000 to fix this, looks like these early model 392 do have some reliability issue?
