Here is our 2006 Buick Lucerne with a small antifreeze leak, most likely Intake manifold gaskets (seems to be common). Car has 109,000 Miles. Have never dug this far into a 3.8 before it was a little intimidating at first but this one seemed pretty straight forward. This is part 2 of 6. Starting to take it apart, upper intake removal.
