Thanks for the info, still havent done a compression test on it yet, a few mobile mechanics say it sounds like a head gasket, and from there expierience with 3800's it probobly is, and the mechanics at local shops say it sounds like lim gasket and the 3800's rarely have head or head gasket problems. so I will narrow it down with the compression tes next weekend. would of been sooner but I have two other vehicles, and low funds, so no hurry, can't wait though, I miss the GP.
