Simple fix.....Next time you have it off just cut an access hole under the filter and drain plug...PITA solved.
You think once was a blast? Try doing these things for a living even on a lift when some dumass has left his/her car idling in the parking lot just to make sure ALL THE OLD OIL IS HOT AS THE HINGES OF HELL and it drains out........Fun, loads of it....Yep, many a bellypan has access holes now.....
