1996 993 Porsche Oil Thermostat Housing

Engine

Vehicle Information: Model: 993 Carrera 2wd; Year: 1996; Body Type: Coupe; Total Mileage: 61,000 miles;

After using the extremely helpful instructions in the techsection I just finished cleaning out my secondary air injection ports. In fact I think I improved the system by fabricating a screw in fitting that allowed me to hook my compressor air line directly into the modified check valve body. (success.. thanks for all the great advice) But in the spirit of not leaving well enough alone I decided that as I was under the car it made sense to do an oil change. I was a little short of the oil change interval but as I was there "why not?" Unfortunately, the last time I had my oil changed was at a local porsche specialist (whose argument was ..I have the car here why don't you let me change the oil??) Unfortunately the tech who obviously used an air wrench (and at this point I think a welding torch ) to install the drain plug on the oil thermostat housing. I have been working on cars for 20 years and I never and I do mean never have seen anything like this. My special drain plug socket stripped it. I have used heat, vise grips, cold chisel ... I now have a nub left where a drain plug used to sit. I think the only thing to do is to remove the housing take it to a shop where the solution will either involve drilling or welding. Can you give me some hints as to how to remove this housing?? How do the lines to the front cooler disconnect? Any help would be appreciated. Cheers
