The Ford Barn - View Single Post - Floor jack won't release under load, any ideas?

Most jacks have a simple valve mechanism that won't be affected by the pressure of the load. It just depends on what kind of valve design it has. Older equipment of 3rd world design can be even more difficult to get parts for than older domestic designs and many of those are impossible to get parts for in this day and age. O-rings and seals can be sourced but hard parts may have to be fabricated if something similar can't be sourced.
