I have a 08 T320 with 6400 hours on it. foot and hand controls only, i have had it for 4 years and have always had an issue with the lift arms bleeding off (over a foot in 5 min). since i have owned it i have rebuilt both lift cylinders, removed and inspected the lift Port Relief/Anti-Cavitation Valve and anti-cavitation valve in the control valve. no leaks from the control valve.no external leaks from the cylinders or hoses, it bleads off with engine on or off and with lap bar up or down. if i use the lift arms to raise the front of the machine it does not bleed off. i disconnected one cylinder at a time and caped the lines and still same problem. removed lift arm bypass and i can get a tiny bit of air to blow through it. (very little) with it down. any recommendations? at this point it is more of me not wanting to get beat by the machine!!!!!! I've looked all over online and can't find anyone who has posted a fix for this concern. thanks in advance
