Injector Issue

We were recently on a long trip and had an injector go out on our 2003 Silverado Duramax diesel. The truck had 99,325 miles on it. We took it to a Chevy dealer and had them replace all 4 injectors on the left, or drivers side, but didn't want to take the time to do the other side since we were traveling with a group. What are the odds that injectors on the other side will go bad and should we go ahead and replace them?

    Lb7 injector failure is common. Fix for reliability? Trade the truck for lbz or newer. There I said it.

    Depends on WHY it went out. Maybe it was that statistically probable one-in-a-million bad ones that got through final testing and lasted this long, and there are NO other ones in all of creation like it in that regard. Or maybe you ran some really crappy fuel through it (and all the others, too) that ate 'em all up, and that was just the first one to go.

    So, the answer to your question is not one anybody else can give you easily.
