I think something with your description is not correct.
The focus setting on this camera/lens combination is fully mechanical, and the light path to your eye is following optical rules and is not in any way influenced by camera settings. The light you'll get through the viewfinder may depend on the aperture setting, but with the correct camera settings this should not happen with a M lens (only green button and shooting should close the aperture to the set value).
If the image in the optical viewfinder REALLY stays blurred all the time even when adjusting distance setting, the only possibility is that the optical light path is not as it should be. No camera setting will influence it. Either the mirror in your camera body is not in its correct position, or the lens is not correctly fixed on the body, or an element inside the lens does not stay where it should.
But I still think something with your description is either wrong or incomplete.
EDIT:
The obvious way to discard some of these possibilities would be to try and exercise to focus with the camera switched OFF!
Focussing manually should NOT depend on whether the camera is switched on or off!
