My colleage is worried about the aspect of connecting rod in two rear cylinders (3 and 4). He consider that is not enough lubrication at this point and is proposing me to make a hole in the top (1 or 2 mm) to let the oil fluid there. As I don't understand a lot about and I'm affraid to "touch" this important component of the engine, I would like to know if the gurus of Lycoming can give me their oppinions about. The engine is Lycoming O-320-D1A with 300 hours aprox.
In one of the picture I marked with an arrow the point in which he wants to drill the hole.
