Thanks 930Targa. Failures have been in the cartridge. We do water cool the turbo with a small radiator and pump. The pump doesn't run all the time, but the internals like shaft etc. are not blued and do not have evidence of overheating. I don't know the names of all the internal components, but it looks like insufficient lubrication may have caused some issues that led to play in the shaft and the turbine started rubbing the housing. We have a gauge on the oil inlet and I believe the pressure was where it should be. We did find that ITS replaced the ball bearing cartridge with a non ball bearing when they did a rebuild without telling us. I'll look into some of your recommendations and appreciate any input.
