Of the motor is already out get rebuilt I didnt know this was a such thing on newer motors. I know on old few motors you had to use shims at the flywheel end,I know these do not have that. Not sure how they get too much play. That is unless the bearings are toast in which case you would have no oil pressure. I'm not saying I know a lot about these but I would definitely do some investigating.
On another note, I just got back from camping close to Iliamna and the bears scared me shitless!
