Gave up trying to get the pan off. Got a vacuum extractor. I was skeptical about it being able to get all the oil out of the engine but it worked real slick. Very simple to set up and use. I ended up having to add 5L oil(4.7L listed as refill quantity) to get the level up to full on the stick. So it must have evacuated almost all the oil. With the filter on top of the engine, no reason to go up underneath at all.
