so, my "replaced under extended warranty" exhaust manifold cracked again... basically about 4 years after the replacement. Of course, it is unlikely that GM or the dealer will do much for me. Not sure that I am willing to spend coin on them as opposed to maybe a third party shop. I suspect if the dealer does it, I am looking at more than $1k. :-(
some questions for those in the "crowd", is there a better built unit or are they all part of the basic "design failure" of either the manifold itself or how it was used / fitted on this engine? Not sure if I can do the job myself... I have the heat shield off and can see the crack in the lower portion of the front "Y" just before the exhaust to cat / muffler connection. My big concern is the breaking of bolt and issues thereafter... ie. once you head down a "hole", you have to get to the end one way or t'other.... maybe if I don't talk about it, it won't happen...
Second, with only two years, do I need to replace the exhaust gasket itself or is it a possible re-use.
Lastly, any gotchas that might make my decision one way or the other.
Thanks for any comments and guidance.
PS. dealer just "quoted" a $700 plus figure depending on what / how it comes off (ie. bolts and such)... it only took them 2 days the first time. :-(
