Gunny...between us, I would bet a lunch it is a cylinder head. In fact, I'm anxious to find out when it was replaced. A little interesting fact. Early 06 H3s with bad cylinder heads replaced prior to March 2006 were most likely replaced with heads that had the same problem as the original. Some of us who were around in the beginning will remember that in early 06, there were no cylinder heads available for service. The reason was GM was switching over to the new hardened head. But, some can fall between the cracks or a head was replaced before the new heads were made for service. GM screwed the pooch at times.
