Here we go back to this oil plug thing again... I was out of town for a couple of days. Wes H. hit it on the head. My 128 and 1450 have the same type of oil plug, with STRAIGHT threads, hex head, and a shoulder with a gasket. The shoulder seats on the bottom of the pan and the gasket seals the plug. When you loosen it, it's NOT a gradual loosening like when you loosen something with pipe threads. You "break" the torque on it and it comes out easily. That's my story and I'm sticking to it... I may be young but I'm not stupid either....
