go to the parts store, and get a uv dye kit, with a blacklight pen. add the dye, run the car, then get out and find the leak. if it is leaking into the combustion chambers, it will still fluoresce at the tailpipe, and be visible with the light. the kit costs like 15-50 bucks, depending on how fancy you go. can be used in oil, a/c and water stuff, to find almost any leaks.
