The other is Time-Sert.Well, sounds like you overtightened the plug/bolt and stripped the thread in the aluminum crankcase. Heli-Coil is the fix for this - there is another method out there which I don’t remember the name and have never used it. But Heli-Coil will definitely fix this. Good luck
Might try and use a screwdriver or something similar to pry down as you try to remove the plug. I also like the idea of trying to affix something to the plug and pull and unscrew at the same time. Might buy a cheap allen and affix it to the bolt, you may have to clean the oil residue off the plug to get it to stick. Although this might force you to buy a new plug.Any idea how to get the drain plug out? It just spins whether I turn left or right.
