This is an all too common problem with supercharged 3800 series engines. GM used a plastic lower intake manifold gasket that would break down over time causing coolant to leak into the oil. If left unfixed, it would get worse to the point where your engine starts knocking from poor lubrication. Your oil will look really milky as a result. This engine had only 60k miles on it when I replaced these gaskets and its a good thing I did. GM makes a newer revision aluminum gasket set that fixes this problem. You can get those from a GM dealer, they are the set that has locating pins, the stock ones did not, but these do fit fine.
