need help on LX665 NH skid loader

Hey guys I am doing some maintenance work on our skid loader and I have a question. First let me explain the problem. When you operate the machine the bucket will tilt forward on its own. It will do it whether there is a load on it or not. In other words if I am just driving it from one spot on the farm to another it will start tilting forward . It has gotten pretty bad as of late. If it is tilted back against within about ten seconds it will be tilted forward at least an inch worth of cylinder stroke.

I was told by a NH dealer that if I took the lines off one of the tilt cylinders and put pressure to the other side if it leaked it would be the cylinder packing. So I tried that today. With the tilt rolled all the way back I took the hose off the head end of one of the tilt cylinders and put pressure on it by holding on the valve to put pressure on the rod end and see if I had leakage past the packing. What I found has me confused.

When pressure is applied to the rod end of the cylinder with the hose off of the head end I get no oil bypassing the packing and coming out of the hose fitting. Instead I get oil coming out of the hose that is off, under pressure and in large quantities. The only thing that I can figure to explain this is a leaking valve body. In my mind in an open center system when pressure is applied to one end of a cylinder the hose that is on the other end should not get oil coming out of it.

What am I missing here? Is it leaking past the spool from one work port to the other work port? Did I just not do something right? I sat and looked at the thing for a while and I cannot figure out what it is. I am sure it would be quite costly to take and have fixed at a dealer and if I know where to look I am sure I can fix it on my own.

Sorry for the long post, but I am at a loss. Anybody out there that can help me?
