| + | The cams get oiled by drainage from the rocker boxes and splash oil in the bottom end. \\ | ||
| + | Oil flows off the pushrod side of the rocker boxes through the pushrod covers, into vertical holes in the lifter bores and into the gearcase. \\ | ||
| + | Oil falls on the cam lobes on the way down this hole. Some of this oil is transferred between the gear teeth. \\ | ||
| + | The rear intake (#2) cam gets a little oil spray from the right case oil feed galley through the small orifice underneath the open cavity in the case. \\ | ||
