I dont know what went went wrong with that link.Thanks Dan...I'm not sure I could follow that youtube video link...it first went to a Montana game camera, with grizzly bears, moose, and a fox that was always running around with something dead in his mouth...) (reminded me of my backyard). Messed around some more and got a great video of a guy taking apart a backhoe valve body and a kid helping him, ferkn hilarious but very helpful, then a video from 1950's on breaking down a valve body. Anyways not sure if any of these were intended to be the link you posted, but took me to some very entertaining and helpful video. My take-home message is I'll be pulling that valve body and rebuilding on the bench in the shop. Thanks again for your help!!
If you have that many leaky valves something external was causing problems. I would look very closely at the tank return connection(s) since excessive back pressure on the tank port is the usual cause.
