Does anyone know where to go look, to find out about an oil A/D on a C-140A? Just curious what the "oil A/D" may entail and don't know where exactly to go search for information.

(edit: I know the O-290 was not standard in the 140, but the one in question has it installed).

Thanks in advance.

It's probably the OIL PUMP AD, which is common throughout almost ALL Lycomings. If that is in fact the problem, I used this solution:
