February 26, 2011Sorry about your luck, but certainly not the norm.
March 21, 2011REVISED: On bad motor,on feb 24 when motor went bad it wasnt same as wat happened in jan,this time instead of droppin valve they determined that 2nd new motor had a hairline fracture in piston on #2 cyl and it just burn up into lots of pieces and all went to oil pan,only rod and wrist pin left,also burned up $400 starter which GM did not want to replace,but service mng took care of it.Hopefully this motor will pan out to be a good one.

March 22, 2011Hopefully you have better luck that is definitely not a normal or common problem from Chevy but glad to hear they took care of it all.
