UNCLE - I give up.
I made a bigger mess with my new vise grips. (the good news I got free vise grips from Sears - their "forever" warranty really works).
I think it is time for vaccum extraction. Next time the car is at a garage I'll have them try to remove the plug with a air chisel.
One of the posts in the archive talks about using a little pump on drill instead of topsider. I think I'll give that a try.
Thanks for the suggestions.
