The above picture is from the bottom of my dry sump tank. It is the drain plug. It should have never been re-installed in its current condition (neither Chad nor I did it). It is about an in above a cut-out hole drilled through the bottom diffuser on my 818R. Tomorrow, I am going to try to adjust the dry sump tank downward so that the plug is at least flush with the bottom of the car.
Here is what you are looking at. It is a plug that used to have a hex socket in the middle of it (now pretty stripped). The female part is -10AN straight thread (7/8-14). I don't have to get it out right away, but will when I change the oil next. There is about 5 quarts of oil above the plug. To get at this part, I'll need to jack up the back of the car and put it on jack stands, so it is not straightforward. I plan to use a -AN10 plug with an O-ring when this part is out. I'd like to start simple and move toward "nuclear" options as the other fail. Here is what I am thinking...in order of simplicity...I'd like your feedback.
1) Try the hex first and twist it a bit to see if I can coax the plug out
2) Tap(pound) a torx bit into the hole and see if I can get that to grip.
3) Use a tap extractor in the existing hole and take out the plug, hoping the tap extractor doesn't break. (and not having to drill the hole all the way through)
4) Drill the hole round, get a left handed tap and put in a short, left threaded hex head bolt to take out the plug when the bolt bottoms.
5) Drill two opposed holes at the edge of the plug and use a pin spanner wrench to take out the plug.
6) Carefully use my dremel tool and a tiny cut off wheel to cut a 3/8 inch square hole in the plug to put the end of a socket extension in to remove the plug.
Any other ideas.
This is a serious issue, but I wanted to have some fun with it. You are all really good at this stuff. I value your input.
