I am looking at buying a 2004 duramax and the owner just told me that he was replacing 3 of the glow plugs and one of them broke. has any one had to remove a broken glow plug and how difficult was it. how should i approach this and why would 3 glow plugs go bad. by the way, it is an LB7 and i have never owned a diesel before so a lot of this is new to me. Thanks.

If it broke off in the head you are screwed. Everytime we brake then at the dealership we replaced the cylinder head. Yes the whole cylinder hear. You cannot heli-coil it due to super high compression while under boost. DONT buy the truck or make him get it fixed first. Its about a 3500.00 repair. Sorry
