white smoke, head gasket?

Have you drove it any? How long have you let it run? Enough to get the motor to normal operating temperature? After I replaced my upper & lower intakes last month and started my '90 GT, it spit some smoke out of the tail pipes and there was some water coming out of the pipes too. I let it idle for over 5 minutes...and nothing changed! I was freaking out at first, because that had never happened to me. It was really cold the night that this happened too, so I know that had something to do with it. Because when I took it for a quick drive and came back...the smoke and water was gone. So really it was just condensation that was coming out of the pipes...and it looked like it was smoking some do to the cold weather. So maybe you'll be ok. Have you checked your oil & water? Any water in the oil? Or oil in the water? Those are signs of a blown head gasket.
