Maybe I'm stupid, but I can't figure out how to get the oil pan off of my 89 commonblock with the motor in the car. I took all of the bolts out, and the pan dropped down a bit; however the the oil pan hits the water pump. It hits one of the bolts on the water pump that holds it together. You can move the pan around, but it is snug at that point. The lip of the pan(where the bolts go through the pan) is sandwhiched between the flange on the water pump and the block.
