More common to find than the water pump even. Not a real cheap job to do correctly, which a lot of shops lack the knowledge of how. 3.8L, lower intake same issue as the other engines, and the bonus, upper intake, or plenum likes to crack due to heat exposure from the EGR system and leak coolant under the throttlebody. Eventually leads to outright intake rupture and hydrolocking the engine. I don't believe the 3.8L was offered that year in those cars, but just a heads up to those running series II 3800's.
So what's the best thing for me to do?
