Driving down the highway yesterday, low coolant light came on, then the check engine light. Pulled off highway, poped hood saw nothing wrong, shut engine off, checked radiator, checked oil, no antifreeze in oil, went to restart, all kinds of white smoke ran rough, shut engine off, looked around engine compartment, saw nothing, went to restart, would not start, had to have her towed home. Any ideas ?

Sounds like you might have had the infamous 3800 intake manifold coolant leak....unfortunately it wasn't caught in time.

Update on my sick car....It was the upper intake manifold leak (shame on GM) Went to parts store and got the new improved intake manifold, oil and filter, spark plugs, antifreeze came to a total of $218.00 for everything. Took about 4 hours to replace, and it's not that hard of a job. And she runs Great... If you have the OEM manifold on your car, it's a disaster waiting to happen, I was lucky, we got the engine off before any damage could happen, you may not.

Thanks for the update.
