Manifold bolt(s) broken. Heard it's a common thing. Really disappoints me about my trust in gm.
Exhaust manifold bolt breakage,I'm writing in regards to my 2001 GMC sierra w/5. 3 liter motor,I have recently discovered a bolt broken off on my head that mounts my exhaust manifold is a defective or inferior product used by GMC this repair should not be necessary for any vehicle if the proper materials were used during original assembly of the vehicle by GMC or any other company in that regard,this repair is a very expensive according to my mechanic to the sum of $760+tax to repair and if it is not fixed it can lead to catalytic converter failure amongst other emission failures as well and possibly fire in the engine compartment as well due to excessive hot exhaust heat escaping from the broken bolt area into engine compartment,as for this complaint I have done some research on this matter and have found a large majority of other GMC owners with this same problem and are not very happy with GMC's inability to own up to responsibility as a manufacturer to fix this obvious and expensive defect due to inferior or improper material used on these vehicles,so any help with this matter would be greatly appreciated by all GMC owners affected by this consistent problem. .
