No need to drop the oil pan unless the grommet and lower o-ring are so severely hardened that some of the chunks fall in when you remove the lower tube. Do you know how to tie a clove hitch? I just tied a couple of clove hitches around the lower tube with light rope then wrapped the other end around a large pry bar. Found a judicious spot to pry upwards and it popped out very easily.
