Heads up on 6.7 Cummins

[Wrench]

It breaks underneath...

Exactly.

The bolt typically breaks under the nut, so that weld won't help.

Thanks for the visual.

They're all married together so they don't fit through the head like just a nut and broken bolt can.

I just disconnected mine for now. This is the kit I’m planning on using when I get around to it. Quite a bit cheaper than the Banks if you’re just worried about the grid heater and aren’t wanting a new intake.

Was there a change with newer trucks to make this more prevalent? I didn’t know it was an issue but from this thread and what I have been able to find on other forums of people having it happen it’s all post 2017ish models. Does anyone know personally of this happening to an 07.5? When did this start happening?

To the best of knowledge, it is the same grid heater used on all of the 6.7 cummins.

There may have been changes in the EGR or the heater duty cycle that is driving higher failure rates, if that is indeed the case.

Again, everybody - jiggle test

Am considering this option also, anyone with feedback after doing this?

But the bolt breaks under the nut... And it's already through...

And the nut is welded to the heater....so it sits in the intake and throws a code for no contact.. but can't go anywhere.

Is this essentially the KDP for guys with fancy new trucks? IYKYK

My buddies 16 with low miles was pretty scary when he pulled it at 40k, about 1/3 of the nut was gone barely holding on. Charcoal for sure. There are plenty of stories to go around and plenty of fixes too. It is just a crappy design that nobody wants to admit to.

As for tigging up the nut, if I'm going to take it apart to weld it might as well replace it with a coil heater and new intake.
