i hit a speed bump and it pushed my pan up about 1/4 of an inch in the middle but it was enough to block the oil pick up tube . all it took to fix it was take out the oil drain plug and get something very rigid in an L shape , work it into the pan in a way that will allow you to knock or pull down the indented part of the pan . this will open up the space between the pickup tube and the pan allowing oil to move freely .
