I just traded a 2012 2500 with 83k miles for a 2017 3500 with 38k miles. I have had the new to me truck for a week now and I have noticed an engine clatter, while accelerating, that sounds a lot like valves clattering. It also does it at the beginning of a cold start for about second. I noticed when I got on it not only did it clatter loudly but seemed to not have the power the 2012 did. The 2012 has the 6.7, minus the DEF, and it never made this sound. I purchased a B to B warranty for this truck from the dealer. So I should be able to get this repaired at no cost, if it is actually a problem. I have done some research and it seems other folks on other forums have been told by their dealers that this is normal. Before I go through them pissing me off, I would like to ask around to see if anyone here has noticed this and if there is a fix. Other folks mentioned the FCA (fuel control actuator) but this was on 2nd generation 6.7 diesels. Any assistance would be greatly appreciated.

We have a 2017 dodge cummins 2500 6.7 and we have never had that trouble, u might want to call a diesel specialist besides ur dodge dealer. Sometimes they know a lot more than the dealer. It's not right I don't think and unless it has had aftermarket stuff put in the engine it should run smooth. I would be worried that maybe a rod or something could be bent . I have a 5.9 that I drive daily and when the injectors were going out of it it was hard starting and would knock. Also if the injectors were going out of it it would have a lack of power.

Hi Mopar810,

We certainly understand why this would be concerning. If you do proceed with addressing this with your dealer, please know that our team is here and we are more than happy to provide you with an additional layer of support for that process.

Thank you for the advice. I went to the dealer today and they had a tech ride with me. He explained to me that the 3rd generation 6.7 has louder injectors and it is common for them to be louder than the 2nd generation engine when loaded up. To make sure I wasn’t being told this just to make me go away, I called the local diesel specialist shop. He explained it the same. Significant changes made with fuel delivery on the 3rd gen resulting in much noisier injectors.
