Update: MT says there are no internal issues witht he prop. The grease is broken down a bit and getting past the seals. They plan to replace the seals with an updated oversized seal that they hope will fix the issue. I've heard about these oversized seals before and wonder why they weren't installed during the overhaul. Heck, maybe they were. Hmmm...
My ATC opinion is NOT an official FAA recognized opinion, so any advice you get from me is ONLY my opinion.
