[QUOTE="thoughtbelt923, post: 127659, member: 23095"] I'm not super familiar with that machine, but I have a couple thoughts. Do you have a bucket positioning control valve? Just off the top of my head that could possibly cause this if it's malfunctioning. Also, if the lift and tilt are two different valves, but the same part, you could swap them to see if the problem follows the move. That would rule out the valves being the problem. It sounds like something is leaking internally. When you lift the boom, you're triggering a valve to apply pressure to your boom cylinders. In your case, this is also allowing pressure to leak from your tilt cylinders. If you have a hydraulic circuitry diagram(you can sometimes find these through the bobcat parts catalog online) for your machine, you could start there and begin ruling out places where that pressure could leak from.
