Rotax Oil Elbow's
Nice little topic for the festive season.
My 912 installation has no less than five metal Rotax OM right angle elbows in the oil reticulation system.
When installed, about 165 Hobbs hrs ago, they were all a bright/silver colour.
Now one is a dull grey, two are dull silver and the remaining three look like new.
What is the story????😈
