Yes there is! The problem was traced to the oil feed passages in the block that supplied oil to the thrust bearing. Mitsu seemed to think that they could lower the supply of oil volume and raise the pressure of the the oil supply to the thrust bearing and accomplish the same thing, interesting concept but it just did'nt work out that way. There is a certain volume of oil needed by that bearing and there is just no way around it. The answer was to open up the feed passage in the block.=[problem solved]
