I have a 2013 SRT8 392 Challenger that is at 110K and I've had it since 2015. The motors camshaft and lifters decided to give up and now I'm looking for a new motor, but I'm struggling to find a replacement. This car is a payment I would like to not have anymore. If you have a motor to sell, let me know. I need to get a work truck but need this fixed and gone.

2013 SRT8 392 Challenger Automatic 5 speed? (been in storage for a year)

 

Try Car-Part.com to find a motor.

 

Any 2013 and newer will drop right in (11-12 have a slightly different tone wheel). Problem is that decent used ones aren't exactly cheap. Low mileage 392's are generally in the $6000 to $9000 depending on whether you can get the engine by itself.

 

I'll check it out and see what I can find. Thanks for the information!

 

Oh thanks for that information! I actually didn't know that, I was thinking that 2011 to 2014 were similar but now I'll look for 2013+. I was originally going to keep the car but for company and tax reasons, its better for me to buy another diesel truck. I'm hoping to get around my mileage for a motor or buy a wrecked car and part it out. I have the ability to load anything I need and tow it free, I just need the vehicle/motor for not insane prices. I also have a employee that can help with the motor swap also as he does it in his free time. I loved driving the car but I've had numerous electrical issues as well, I'm burnt with it for now.

 

Replacing the cam and lifters would be easier and cheaper than replacing the whole motor. If you replace the cam/lifters without the MDS(or new with the MDS) it would be a selling point. Plenty of info on the MDS failures if you search for it.

 

Please don't spread misinformation like everyone else online.......it's not just the MDS lifters. More often than not it isn't an MDS lifter that fails. Only cylinders 1, 4, 6 or 7 are MDS. There was just a bad run of lifters, period.

 

I can work on vehicles to a point but not really internal motor things. I've been told how bad those lifters are and I want to be able to do that but I haven't had the luck of finding someone willing to help me learn how to work on them. I know mechanics that will do it in a queue and get to it when they can or ones that will help me motor swap a vehicle but not help me with installing cam/lifters. I could just try but currently have a truck apart for swapping a replacement motor into it.

I've heard mixed information about the MDS system. It's like a lot of first implemented components. Many issues off the start then gets better in the future.

 

MDS was designed into these engines back in 2002 (for the 2003 model year release) before the software to even run it existed. 2005 was the first year for MDS in the 300 & Magnum. MDS itself is not the problem, never was, contrary to what all the hysterics say. The LIFTER problem started somewhat early in the VVT engine run (09+ 5.7, all 6.4's). I have a 2005 5.7 with active MDS and 130k+; I had a 2006 5.7 with active MDS and it was up over 180k. No problems. Currently have a 2012 392 auto with active MDS and just over 90k; no problem.
MDS works just fine as long as all the components are good. Nothign will work right if components fail. Here's the real fun part no one wants to hear; it happens to the stick shifts too. bUt BuT bUt BuT bUt MdS.......

 

HAHA right?! I don't believe I was that lucky. My mechanic will be double checking the codes and checking it out because we had a misunderstanding when it came to the components. He is going to check the codes and inspect it again to see what might be going on with the system and hope that its something simpler, but I highly doubt it. I just need to trade it in for another truck for the company. That's all the plan is for this car for now so I don't have to keep making payments. We will see what he has to say later.
