bro in law has a 1998 chevy 2500 Duramax, it's blowing white/gray smoke. The dealer told him he needed eight new injectors, I'm throwing the Bullshat flag on that. I googled ijnectors for Duramax they run about 700$ as opposed to 6.5L injectors that run 60-80 $ Bro in Law has made some poor finacial decisions, got married for the third time:rolleyes5: I'm thinking of buying his truck , I was wondering if there was a way to determine if he only has one or two bad injectors or if the chevy dealer is just trying rip him off. I have no Diesel experience but I thought bad injectors would spew black smoke
