06 Cummins
I have an 06 Cummins bone stock motor wise besides a straight pipe. It's only got 120k miles on it and it's starting to make a ticking/knocking noise coming from under the hood. If I'm cruising down the road and get into it a little bit it mellows out and the ticking goes away. I'm thinking it's either the injectors or cp3. What do you guys think?
