Finishing up my annual condition inspection and the A&P and I were checking connections and nuts on FWF. Everything was tight and secure except when we got to the fuel injector throttle body. Only one of the four nuts securing it to the engine was tight. Two were so loose you could spin them with your fingers and one was totally gone. The engine still ran smoothly.
Replaced all star lock washers, replaced the missing nut and tightened all to torque. We then added four nylon end nuts on top of the existing nuts and secured them - there was just enough room on the studs.
My A&P said this was the first time he?s ever seen nuts loosened like this - especially if no one?s worked on the item. He distinctly remembers checking the throttle body last year and every thing appeared secure then.
Our question: My engine is the Superior XP IO-360 B1AA2, has anyone else found they?ve had to tighten these nuts due to them becoming loose? This could have really ruined my day later this year if not discovered!
