Huh? What do you have for a drain plug such that it’s two parts and has a section that can loosen and go inside the pan? I’m just really curious.I just remembered this one. Last year, while doing another oil change, I unscrewed my oil drain plug too much so that it came apart. Part of it was lost in in my oil pan. I had to borrow a car to go buy another drain plug. On those bad days, just take a look at your kids--hopefully it puts a smile on your face.
