Re: 356 connecting rod oil hole

Oil holes should face the camshaft side of the engine and all should be open to lubricate the cylinder wall expecially on the power stroke. Perhaps you had an "oil burner" and some butcher thought he was solving the problem? A bit scary to think of the consequences if the engine was driven much with the holes closed. IIRC the hole in the rod aligns with a hole in the upper bearing shell and this aligns with the oil feed oil in the crankshaft just at the point when the piston is at (or near?) the top of the stroke. Someone who has had one apart more recently will correct me if I'm wrong on this.
