Can one just remove mains and pull crank down enough to get a graphite rope seal in ?

Yes, it can be done. Your success rate would probably be pretty low. Once again, outside of a dealer environment, I would recommend removing the engine as Sirrotica explained. Once on the engine stand, and upside down, you can get everything really clean. You can also test fit and adjust the pan as needed. Your success rate will go up exponentially. As far as the "Best graphite seal". You need to remove all the main caps and pry the crankshaft up. You should be able to remove the seal pretty easy. Take your new seal and pack it tight in the cap and then cut it with a NEW single edge razor. Then very carefully remove it without changing it's packed shape. Transfer the shaped seal half to the block cavity being careful to center it end to end and not changing it's packed shape. Then fit the second half to the cap, pack and cut. Lower crank back in. Don't forget to apply anerobic sealer to the cap just where the seal parting line is. Not under the entire cap mating area. That will seal that leak point. Factory service manual shows this well. People often fail to do this and almost a guaranteed leak there. Many different opinions about the rear oil pan seal. Personally, I do not use a seal at the rear. I apply a thick bead of RTV carefully to a clean and dry surface and give it 8 hours to dry. Been doing them that way for 20 + years with good results. Seems cork is the second choice in this message board. Not many people have luck with the 3 or the 5 tab rubber seals. Most people know I can be a little cheap. But I recently tried the BOP one piece pan gasket for the first time. It worked well and did not leak. So I am 1 for 1 with that expensive gasket. Good luck with it.
