Message I observed with my pan. The bottom of the pick up is enclosed in a diamond shape baffle. Two sides of the diamond ( left and right) have one way flapper door each like a door hinge. The doors open only towards the pick up and shut towards the oil "kick outs". An oil pan "kick out" is where most of the volume of oil is stored. On a stock Z32 pan that would be driver side of the pan. There is space for oil to go around the flapper doors . This space is pretty small. When filling with cold oil to measure the quantiy, it took 10 minutes for the oil level to settle and go around the baffles and one way flapper door. The oil level would seem very high at first but then would settle down to fill the open spaces in the pan. On a non baffled pan, the oil level settle quick. That is why can check your oil level after a minute of pouring it through the valve cover and see it register on the dip stick. On a baffled pan, the oil level dipstick will show that it is over filled at first but then settle to the proper level because of the baffling was doing its job. Also draining a baffled pan takes much longer because the oil is being held in place by the baffles and the one-way flapper door. On my oil pan I will want to make sure one side of the car is slightly higher than the side with the drain plug to help it drain most of the oil. Basicaly the baffles and one way doors work too well to keep that diamond shaped area where the pick is located filled with oil. I will post pictures of this when I release my oil pan.
