Exhaust manifold bolts

[[__--MUD--__]]

What are the odds that both of your exhaust manifolds are now cracked.... Can't replace them w/ out some proper bolts to secure'em.

I just had mine replaced with the special, upgraded, super heavy duty, mega manifold bolts!!
All is well again!

Thanks seems as if this is a common problem not only with hummers but most ls engines,It sucks that gm has not acknowledged that they should warrenty these fixes when they are fully aware they have a problem because they have already changed the bolt size for any manifold replacement. I always thought if you spend 50k on a new truck the service would be a little better but it is all about the one sale. Loyalty to a specific brand has no bearing on customer service. It was suggested that i crack the manifolds myself because gm wants them sent back if they are warrenty repaired, I found this rather amusing since they would just throw them out and not issue a recall if they found a problem anyhow.
Just venting

I still claim the exhaust is to rigid...w/ the motor torquing the stress is going to be on those rear bolts. There needs to be a little play in the hangers.
