    I raised a car with a different jacck and then put my old jack under it and released the newer jack and it held. It will raise about 100 lbs.

    My jack does't leak so must be by passing internally. It will hold a load.

    Blackhawk S-4 Restoration

    I have a S4 that is complete it will raise fast, but when it is put under a load it will go no further. Any help would be most appreciated. I have changed the fluid and did a little clean up.
