2003 Dodge Intrepid Water leaking from below?

I have noticed over the last month or so that my thermostat has been climbing more so than usual. It does not get to an over heating level, but when it climbs above the half-way mark and I brake or idle, my oil light comes on. On many occasions, I have checked the oil levels and they have been fine. I also get like a burning oil smell from the engine after I turn off the car after these episodes. Most recently, my vehicle seems to be dripping water from the engine area and the back of the muffler. The drips are becoming more prominent, and I know it is not any other engine fluid. What could the problem be? Radiator fluid levels have been normal, oil level has been normal.I am at a loss!
