Over this past winter I had my 1964 Lincoln 430 cu in engine, the transmission, the power steering gear all rebuilt. Im having trouble with the power steering system. Fluid is being forced out through the power steering dip stick tube in the reservoir . . I have purged out all the air as far as I know. No whining noises a first and now I have some whining noise when turning and fluid being forced up the dip stick tube. Im thinking air is somehow still in the system. Im hoping someone will have a solution for me. I also had the power steering pump apart and replaced the seals. No longer leaking.
