A chunk of "weak" oring ended up in a spool/valve?

Just as I figured, in the spool. Now she's working.

Whats your point N.I.W.? all I said I think your problem is in your control valve, Im not getting paid for this so who cares who was right.

Hopefully, the picture was uploaded to help. If not, I'll try again.I tried to loosen the bolt in the 7 o'clock position, but can't budge it. The two bolts in the 5 o'clock position have a line running into them. Could this be the one to loosen? Also, what should I expect to happen when I loosen them (it)? What will I see if everything's ok and what will I see if not? Also, do I need to bleed the hydraulic lines like I do the fuel lines? Like I said, my knowledge of tractors is zilch. But it's great learning. Thanks

Big Kahuna,
Sorry wasn't trying to offend, I was just clarifying, just brought it up so you wouldn't give up on helping find the answer to AshleyBS55's problem.
In my eyes, everyone has something to input, and your no exception, your input on problems can be very positive.

AshleyBS55,
The round part with the 2 bolts is the high pressure supply input, if you loosen or remove it hydraulic oil will come out of there at a very high pressure and rate when the engine is running.
Don't force the bolts, breaking one of them would be disastrous, If you take another picture of the side with the control valve and relief valve I can point where to pull out the relief valve to check for pump pressure. and if your problem is in the control valve it's in that same area.
Looking at schematics it looks like you might have a feed back lever, and that is also known for causing 3 point problems.

If you remove the high pressure supply, even with the tractor not running, be careful. There is an O ring in there that is easily lost.

Let me know if this is the correct pic. It was hard getting the camera in there at the right angle with the fender in the way. So when I loosen this what am I looking for to determine pressure? Again, I appreciate everybody's input and time on this.

Is that a manifold tap block in the last picture? if it is, just take the shiny new hose off. But I thought we were okay and it was working again?

first thing you have aftermarket powersteering, is it still working correctly?
if so we can assume you have good pump pressure.

second is there a valve, or knob on the block where your powersteering lines are connected? if you can please post a picture of this block.
