i found this regarding the 6.5L RMS removal:
Remove the oil pump and rear main bearing. Just for precautionary measures, replace the oil pump with a new one. Inspect the rear main bearing face and crankshaft mating surface for any excess wear / mars. Pull the seal out of the bearing cap use a small screwdriver or awl to remove the seal that is still in the block. Clean all mating surfaces of the oil pan and engine block for the reinstallation.
hope that helps maybe
