Engine Mechanical problem
2006 Hummer H3 Automatic 41000 miles
Brought H3 in for catalytic converter rattling noises, and dealer confirmed the converter needed changing, but they also told me that there is a cracked cylinder head. Can diagnostic testing reveal this kind of problem without getting into the engine? I was in the waiting area for not more than an hour and they return to give this news. There were no recognizable or detectable signs from the vehicle to alert me that anything was wrong with the engine other than the check engine symbol on dash that coincided about the time I began to hear the converter noise. I assume the light came on due to possible communication with the converter.
