The mechanic had to replace a part. Then found he needed a part for the part. Then found he needed a part to connect the two parts, and the part to connect the two parts had to be ordered from parts unknown.
Once those parts are installed, he can run the engine long enough to determine whether or not he’ll need to replace another part. If so, that part will also have to be ordered from parts unknown.
Sounds like we’ll have Miss Lueffie back in good working order about mid-2011. Of course by then some other part will have rusted out and fallen off…
