Ok so I pulled the compressor today and zipped it open.

This is with the top off, the rotor turns freely, no sign of oil.
This is with the bottom off, when I turned her upside down about 2 tsp of oil was in the case.
And the is the inside with the cover off. NO OIL, not even a thin film.
I would have guessed there would be a lot more oil needed to make the compressor run. I was confused though because I saw NO reason why the rotor would not turn. Unless I shorted out a winding due to over heating.
So basically I have only a hint that I should find another compressor and add more oil.
Any ideas guys?
