Well I have been adding penetrating oil, heating with a propane torch and using a long breaker bar with about 3 ft arm but have not been able to remove the plug. I also tried a 1/2 impact wrench but did not budget. At this point I have decided to remove the engine so I can get better access.
Plan is to continue to spray with penetrating oil, and heat and then try a much longer arm and hang a bucket of bricks or similar from it for a few days. May also try renting a 1" impact wrench for a bit more oomph (technical term).
Any success stories of people removing this plug would be helpful at this time as it feels like I am banging my head against a wall .
