I wouldnt buy anything from them. They def tried to pass that pile onto you, so why wouldn't they do it again. Glad you got out of it
LB7 & LLY have the same compression ratioThere are also certain advatanges to lb7s... They have a higher compression ratio and fewer emissions than all other duramaxs which yields higher fuel economy. 04 should have an egr on it but 01 and 02 didnt even have an egr system on them just a vent tube. I would cautious with this dealership though, if that other lb7 had the issue twice before the bearing were probably already chewed up throughout the engine and they probably knew that. Good look with the delima :thumb:.
You have a federal emissions trucki have a 2004 LB7 it has no EGR, just vent tube down front of engine, and no CAT! ordered truck new so must be last year for no EGR an CAT
