Engine knock from exhaust when cold

[muncie21]

Broken exhaust bolts are pretty common in the 6.0 and 6.2s. Mine would tick when cold and then taper off as the engine warmed up.

Thanks Sparkvark (and gpd4) I'll have to take a look at them! Being a lifetime CO vehicle and having 140k, I doubt it, but it's certainly possible I guess, especially with the heat. I'll be back to you on that!

Also with the 4.8 and 5.3's.
