This is a pretty stupid question, but that never stopped me before. Which way does the
oil flow through the filter? Is it in (from the
oil pump) through the smaller holes around the circumference, then out (to the bearings, etc.) through the larger hole in the center, or vice-versa? I was looking at a filter last night and couldn't believe I didn't know the answer, but I guess I was sleeping in auto shop the day we discussed the engine's lubrication system.
