Hi Price,
I'm pretty sure that your servo is still leaking internally. The fluid
leaks past the servo cylinder seal and into the vacuum chamber from whence
it eventually finds its way to the inlet manifold and is burned by the
engine and comes out the exhaust pipe.
To check loosen a few of the nuts and bolts on the bottom of the servo
chest and pry the cover back a little keeping the gasket  against the
cover. If fluid leaks out retain it and add a few drops of water to it. If
the that fluid turns milky around the water it is brake fluid and the servo
seals are leaking.
Hope that helps.
