GM made their intake manifolds out of a plastic resin on the Buick 3800 V6 engine. They routed the egr valve through it which causes a heat build up that wraps the intake manifold allowing coolant to go into the engine. My repair bill was $803.76 plus one starter $189 that broke when the engine siezed. From reading on the internet this is a common problem with the engines with the plastic manifold. The dealer that fixed my car aid yes it was a design problem and that he had another car of the same make and model as mine in the same morning as mine. Same problem and that he had one the week before. In my case the engine did not lock up as I as going down the highway but this could be a dangerous problem for someone going down the highway and thier engine locks up.
