Pressurizing was the first idea. Think it has way more risk to it.
Ideally one would vacuum out the drain hole while there was still some oil in it. Give the liquid a chance to pull any solids out with it.
As Petah said the whole thing is more of a thought exercise or experiment more than a practical way to pull sealant out.
Makes no difference to me since I have no stake in it anyway!
