Scott & Gil thanks for the supporting information. Every builder is going to need this diagram and procedures on securing that plug. Iam printing it out for my manual. Since we are here on the subject of oil I did send in a oil sample for a baseline analysis. Next question, tightening the oil filter. I can?t get a socket on the filter for a torque setting so I went on a builder suggestion in that after a coating of oil is placed on the rubber gasket of the oil filter I should tighten the filter to gasket CONTACT and then 3/4 of a turn then safety wire which what I did , seems pretty snug when I tightened the filter. Temp of gasket was air temperature of 65, I would think if it where 80?s it would have been easier to tighten as the rubber squashed. Now Jon you mentioned the asbestos. When ever I was drilling asbestos at work we sprayed with a liquid on the hole and drill and than the material was drained into a bag,sealed and shipped off for disposal. I would think there would not be a issue here since the tightening would close that or seal that opening on the washer. And it maybe a different material now. Curiosity how would one torque the filter if there?s no space for a socket? Now my buddy just bought the RIGHT ANGLE adapter for the oil filter which is pretty nice since it?s easier to torque and remove with no dripping oil. He paid $350 for that RIGHT ANGLE filter mount. Is there any cheaper or is it not a good thing to install? Maybe Lycoming or Vans can do the mod before we pick up our engine. Thanks, welcome to weigh in. Oh just a note that I bought a oil two gallon drain JUG. What?s cool about it is that it?s square tall, has a 2? cap and a liquid release lever at the bottom it?s a water jug and can be found in the display for fresh water. Then it?s real easy to drain the old oil back into the empty quart containers. The jug is CLEAR plastic. The store is a national food chain store but maybe found else where Made a drain tube for my quick drain plug. 24? of 3/8? vinyl tubing cut in 8? & 16? and put a valve in between the two pieces. The valve in bought was from a national farm supply and is used for chemical spray applications. Oh the jug cost. $9. The valve was $10. Thanks Ron in Oregon . Love flying the 9A at 8500? on the Dynon autopilot,Catto 3 blade, just saying.
