Well guys, I loaded the system with oil and a can of refrigerant while I searched for a UV dye. The next day, I found puddles of dark oil under the middle of the car. At first, I thought I had either a motor oil leak or a tranny leak. Upon closer inspection of the oil in the driveway, it seemed too thin and too dark to be either motor or tranny oil. My guess is that the evaporator is shot and leaky and the oil is actually coming from a leak at the evap. I think that the oil leaked out and mixed with all the gunk that's under the car hence giving it a very dark appearance. Do you guys think that my assumption is accurate. If so, I am planning on a complete system overhaul with a new evap, drier, compressor, expansion valve, and seals. My compressor was very loud and thats what prompted me to add oil. Now the engine is quiet but the leak is extensive.
