This territory been canvassed before. It does seem strange to vent a bearing just as the main load suporting film (at normal revs) is required to form, but Austin obviously had some firm basis for. Anyone know if the FN basis engine was so treated? Perhaps it vents air as well as oil. On the upstroke oil must enter. Many remetalled rods have the drillings without the trench, a reasonable compromise. Having read too many books, when remetalled I plugged the holes with screws now immovable. Since done about 20,000 miles but not above sustained 4,000 rpm.
