| My truck is a 2004 chevy silverado 2500 with 94000 miles and the rear driver side exhaust manifold bolt head is busted off. this is not the only chevy/gmc 4.8,5.3 or 6.0 engine that has this problem. millions of others have this same problem and from this failure it can lead to future emission problems, catalytic converter problems, exhuast leak in the engine compartment leading to exhaust fumes being leaked into the cab of the vehichle which would be carbon monoixde poisoning. this is a major issue that gm should take care of as a recall !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! | |||

| Four exhaust manifold bolts have broken off since i've owned this truck and the manifold has cracked. it is a design flaw that occurs in many of the similar v8 equipped models and has been well documented on the internet. this should be recalled by gm. this problem also leads to faulty emission readings by the vehicle and the check engine light will go on and remain on until this expensive problem is fixed. | |||
