Thanks Pete, It's a year old problem when I got it. But I spotted you and 2 others on this thread who have some expertise with power steering I haven't dealt with before.
Probably a new pump would fix it but those things are expensive and hard to find. Hate to spend a bunch of bucks and find out it is something else. Mine has the T screw valve you are talking about but wide open doesn't really help the flow. I rebuilt the steering cylinder which helped a little. Where is this relief valve you are talking about that may have a bad oring? Is this on the other end opposite the T screw?
To road it to town to a dealer and get it flow rated is probably out of the question. I can remove a line or two and get it to spit and dribble into a bucket to get an idea of the flow.
There are a couple check balls in the pilot valve that I've had out and found no blockage. They are a burger to get back in. It has some type of spool and check valve to bypass flow to the oil cooler. Maybe I could block off the oil cooler and see what happens. This would assume the excess would bypass in the flow divider. I don't run it enough to need a cooler anyway.

But, on the other hand, there is a secret language that our mechanical companions readily do speak. It is an interesting form of communication that involves all the senses of the listener. In this series we are going to investigate and learn the basic rudimentary skills of understanding this lingo.
