As you all know my duramax has been smoking, ive started putting in powerservice diesel kleen. The blue smoke has stopped for the most part, but now there is a systematic clicking coming from my engine, it could be pinging but it sounds like a ping or click. The techs at the second dealer are telling me that my engine might have an injector that is "heading south" but has some way to go. How can I help speed up this process and what is the click or ping?

hmmm....

drive around at wot,jk, sorry cant help u with that.

injectors

is it bad to drive it? Im going to put my chip back in i think
