Evening folks: Well surgery is over and the beast euns without leaks, exhaust gasket yet of course from the effort to be replaced, but all is good.
The bad woird is that a check with the dealer at his secret files:) told us on the very first line: After having removed the engine from the vechicle, ref subsection......removing engine etc etc. the oil pan is accessable for service as required.
So a 9am start, resulted in a 5pm drive away, can't complain about the time all being considered, so tks to all who replied, and those who read the post and had a good laugh and were glad it wasn't them, doing it:)
hope to likewise help someone else someday.
