6.4l engine 2 issues - Took it to a mechanic may most likely need rocker arms & 2 fuel injectors - parasitic draw draining the battery when turned off ( ive paid to replace the egr valve that may have fixed this problem unsure until i revisit the diesel shop ) Be prepared to spend 3-4k getting this truck fixed i want to be upfront unless your a diesel mechanic or know someone to fix for a very affordable price i have no time to mess with, automatic liftgate flatbed worth alot alone as well as many other great parts truck valued at 10k+ fixed up and can haul pretty much anything including commercial equipment. 3500 FIRM
