My buddy with a Duramax had to replace all his injectors at 120,000 miles and got me worried - I have about 200,000 miles on my 2006 Dodge. How long do injectors typically last and how does it diff...
First generation Duramax, if that's what he has have injectors that are know to fracture. They do not make new bodies anymore and all replacement injectors use old good bodies which is a good thing because it means they weren't ones that failed earlier.
