My engine had a tiny, mysterious oil leak. After each flight the rear of the engine had a thin film of oil on it. Not always enough to drip, but enough to feel or to see on a clean rag. I have never been able to find the source of this annoyance until this weekend.
Don Vance read of my difficulties getting the O-rings in my landing gear to behave and sent this piece of advice on the subject. It is so good to receive technical information like this. Thank you Don!
There are not many parts of an aircraft that need plating, but the baggage compartment lock is one example. Mine had significant surface rust and so needed restoration.
