"..I’m a woman and blond so what can I say.."
I think you've said all that can be said. Just kidding.
T-Bars are solid metal, so the oil/grease may be from lubing the splines during manufacturing or somewhere else. Hope that helps, from a blonde, take it for what it's worth.
Good luck and be sure to leave a finger width or two between the bump stops, after doing the Crank.
