I really need your help. Two days ago it was time to change my glow plugs 'cause #4 was bad. So, I decided to have all 8 replaced. I took my truck to a shop to get the job done. When I came back job was done and here is the thing. They told that 2 glow plugs threads went bad when they were trying to get them off. I almost kill the guy when I found out that is a major work to get it fixed. Any suggestions as to get the problem fixed so next time I change the glow plugs I can do it myself. I don't want to do an overhaul. My truck is only 65k miles 06 2500hd LBZ. Truck is working fine now but that #@!@# really worrie me. PLEASE
BTW I'm overseas (south america) and down here there is no GM dealer.
