I am glad you found the problem, good troubleshooting. I was going to add oil lines and rear scavenge pump to the list of troubleshooting items. I have had it happen once that the main oil supply line was collapsing and believe it or not, oil pressure was normal, but over-tempted. I have also seen where the aft scavenge pump was starting to fail, thus letting the oil cook back in the turbine before returning it to the system.
I bet your FE\'s appreciate how \"picky\" you are when troubleshooting your engines. Nothing is worse then shutting down a good engine because of oil temps.
Best Wishes,
Greg
