I cut the safety wire off the oil drain on the right side of the oil sump and removed the plug. Luckily I had the bucket in place under the engine to catch the oil. About two cups of oil came out before I was able to install the quick-change oil drain. The drain is a Saf-Air F P5000 from Van's. I applied the anti-seize and tightened the drain. It needs to be safetied.
