    Re: 2019 Cummins Loud Tapping Noise

    Today, I got a call from my FCA case manager. I assume she heard about NCDS because she was a lot nicer this time.

    She called to confirm if I would be fine with a vehicle replacement. She said the "next step" is going forward. No specific details yet though. She said she will get a response early next week (I guess from her superiors).

    I have my fingers crossed.

    Good deal.

    Hopefully you can find what you’re looking for in an 18.

    Finally heard it on a computer. Sounds like the old GM 6.2 v8 diesel motors LOL.
    That's not normal for a Cummins, hopefully its nothing big and dealer sorts it out quick. Keep us posted please

    Remember when I said the CP4.2 was noisy as ****.

    This is the noise I’m talking about. I may be wrong on it being the pump. But I’m pretty confident that’s what it is.

    Well if it is, maybe the damn thing is starting to beat itself to death...

    I have always heard the buzzing noise of the cp4.2, but that noise originates from the front of the engine. This noise originates from the top rear of the engine, and it's a sounds like it has a direct correlation to engine rpm not the pump rpm.

    Does it go away above a certain RPM? Mine rattles like crazy at idle but around 1400rpm it stops

    Got a phone call today, and they told me the noise was normal...

    Anyone else with a 2019 have this noise?

    Hard to tell from listening to the computer but that sounds an awful lot like valve train noise.

    Loose rocker arm, lifter issue something like that.
