I have a Bobcat 864 and the arms only lift up, the bucket only tilts down and the 4 in 1 only operates in one direction. All the functions can go in the other direction but it takes minutes to get them back. In the direction that they all move the operation seems to be normal. Checked Hyd level and it is good, hyd oil looks good and machine runs fine. Seems like there may be a check valve stuck or something similar. Any help would be appreciated.

Your aux hydraulic circuit is stuck on. A loop hose between your front quick couplers will verify this.
Can be a result of a electrical problem feeding power to one of the 2 coils on you hyd valve bank, or a bad spool inside that coil that has the needle jambed in the open position.
The latter being more common
