Latoya Bradley+FollowWhen Cummins Diesel Got EGR DramaEver wondered when Cummins diesels started using EGR? The real EGR system didn’t show up in Dodge trucks until mid-2007 with the 6.7L engine—before that, the 5.9L had a sneaky cam trick that kinda did the job, but not really. EGR helps with emissions, but a lot of owners say it just adds headaches (think carbon buildup and reliability issues). No wonder so many folks want to delete it! #Cummins #DieselEngines #CarTalk #TruckLife #AutoFacts #Cars11Share
