I tried very hard to take the oil drain plug off my pan, seems like its welded on, or I am just weak, haha, Anyway, I need to change my oil, and have a new filter, since I can't get the drain plug off, Is it easy to pull the pan? Would be nice to clean it out not knowing if there is sludge or? in it anyway. Will the pan just slide out or do I need t lift the motor up some? Thanks...
