What year is your cadillac? Are you sure its not trans fluid? If its anywhere from 96-98 just look for a new engine. When the head gaskets go on Northstars it's usually not the gasket itself, the threads in the block for the head bolts pull out which causes the gasket to leak. And it's usually the rear head for some reason. GM released a thread insert kit (similar to heli coils) that your supposed to repair it with. But they usually don't work very long.
The other year engines do the same thing but not as common as the 97's
