Bob,
Many moons ago I read about changes that were made in the pump supplied
to Lancair.  Oildyne has many options available.  We even used one here
at work for a back-up steering system.  I am really only familiar with
the last supplied configuration.  I am curious to know what part number
was supplied in 235 kits and when the change may have occured.  Is your
pump the original supplied with the kit?  The part number will reveal
any configuration differences.  I can certainly envision a configuration
that bleeds off fluid easily in both directions to produce the behavior
you describe.  If there are different versions out there, knowing what
they are will help in discussing hydraulic system issues.
