I just heard back from the last dealer I talked to and they have the repair kit and they will sell it to me for $ 80.00 , I will be on my way 120 miles round trip shortly. This is the last of the kits like this available presently. A new valve is $ 1100.00 and I think I will order it as well. If parts are that hard to get I will repair this one and have it in reserve should something happen to the new one. Such a major problem for a small part.Sometimes, the supplier may put something in the casting. Could be anything.
