Lincoln/Mercury Repair: My car has sprung a major leak!!!, crap job, 1995 mercury tracer

Question
Hello, I have a 1995 mercury tracer 1.9, and about three months ago I had the heater core replaced, well I now have all the symptoms of a blown heater core once again but this time it is worse. I have to fill the coolant reservoir almost everyday, and the water seems to be leaking onto not only the passenger floorboard, which is what happend the first time, but on the driver side too, and it seeps back all the way to the edges of the back doors.. and I also have water leaking somewhere in my trunk.I have had many problems with this car like, replacing the engine twice, and the thing that guides the dipstick down into the oil pan break, that is just to name a few.  This car has sentimental value to me and I don't want to get rid of it, so I want to know the problem before I go and sink more money into it than I already have.. I am hoping you can help me...
Oh and by the way, we checked the reservior tank and radiator for leaks and they where both fine..
