My opinion is still the same as last time this came up. The LIM gasket needs to be replaced. With the GM 3.1, 3.4 and 3.8 V-6's, it is not a matter of if, but when it will go. I have 2 cars that I am doing this repair on this month. You should try and get this taken care of ASAP or it could end up ruining your engine. Coolant and oil mixing is not good for making your car last. Since you have the N/A 3.8, I would replace the upper intake while you're at it. The Dorman one comes with all the gaskets needed for the upper and doesn't cost that much more than all the gaskets bought separately. Good luck.
