| It was determined that the drivers side exhaust manifold bolts were snapped off from the left side of the engine and it was only being held on by 2 of the original bolts. this could have fully broken off while the vehicle was in motion and jammed into my steering shaft! after a very simple google search about gm 6.0 engine exhaust bolts snapping off, i discovered this has happened to thousands of engines of the 4.8, 5.3, and 6.0 size. *tr | |||

| I am one of the many reporting broken exhaust manifold bolts on my truck. i had 3 studs rattle out, 2 break off inside head gasket and only 1 remain in tact. truck is in great condition otherwise and has had excellent service record. only problem now it is costing me $2500 to pull engine and send it to a machine shop to have the final stud removed from head with only 170000 km's on it this is ludicrous. i am a very unhappy customer that this is not a recall as it happens to almost all of these trucks between 09 and 2007. and it is a fire hazard as well as bad for emissions http://www.youtube.com/watch?v=0yg6wlbnzgi&feature=email&email=comment_reply_received | |||

| Ever since i bought it in oct 2004, i felt this jumping of the truck after i stopped and started to accelerate it would do this, i called in and they told me that maybe because it was new, it may be doing that , i took it in last week because the engine light was lit and there was a strange burning smell on , it and there was also the recall of the back seats, and a light sensor loose, it was returned to me after a few days, and they said that it was because the gas cap was loose? that was the worst excuse that i have heard, i am still having that problem, but i just don't want to take it anymore because they are going to come out with the some lame excuse , and still have the problem. *jb | |||
| ENGINE AND ENGINE COOLING - EXHAUST SYSTEM | |||

| 1999 to present 4.8,5.3 5.7,6.0 liter engines from gm have inferior grade metal in the exhaust manifold bolts causing them to break. the vehicles will have exhaust leaks and false readings to the oxygen sensors.the exhaust leaks of raw exhaust gases in to the atmosphere translate to extra pollution into the atmosphere from all these vehicles . the other matter is that the computer on the vehicles isnt given the correct oxygen sensor reading becuase of the leaks ,either gas leaking out or air being drawn into the exhaust stream causing the premature failing of catalytic convertors. the computer on the vehicles may or may not warm the customers with a light based on the severity of the exhaust stream leak gm put out replacement bolts for this problem ,but that only fixes the people's that have the time and or resources to visit the gm dealers. alll the rest of the vehicles and their owners are reponsinble for getting the old bolts drilled out and trying to get the vehicles fixed on their own. lots of pollution taking place and money being spent on a problem that could have been avoided with some proper grade fasteners. and this is on about 12,000,000 cars trucks and suvs. this is being written from someone who has had 25+ cars and has an automotive engineering background. and someone who spent money and precious time on this issue and realy should not have had to. | |||
