I been having a problem with the exhaust manifold bolts breaking off. i spent a ton of money replacing o2 sensors over the last 4 years. i've just currently found out that the o2 sensors were not bad, it was actually the exhaust header bolts breaking allowing my emission system to malfunction. i've had 3 bolts replaced 2 months ago at a tidy cost of $1000.00. one week ago i was driving down the road and smelled exhaust fumes in my truck cab. i took my truck to my mechanic and he found 3 more bolts on the right side of the engine broken off. not only am i without a vehicle (because at this time i cannot afford the repair) i think general motors should correct my problem and pay for previous repairs. this is poor workman ship on their part not to mention a serious safety hazard. all gm trucks manufactured between 1999 and 2007 with v-8 engines have this problem. gm should man up to this issue and recall and repair the faulty exhaust manifold bolt problem. i for one think this could be a safety issue and environmental concern. my truck cannot pass an environmental emissions test at this time. *tr
