I have to wonder.... interesting topic....
I kept on thinking of ways to put positive pressure in the bell
housing.... to assist the rear seal of my TR4A, etc... I even
thought about running a tube from the front of the car, to take
advantage of the positive pressure there.... and I figured some cool
air there wouldn't hurt...
Here, you say you put a scavenger tube in the bell housing....
I have to wonder... while I trust it did, indeed, suck up anything
that came out.... might it not also have drawn oil through the rear seal?
Just thinking aloud here....
