Hello Net Sure is quite today. As an update to my turbo saga, I disassembled the center section today and no parts fell out. The oil seal on the hot side is some metal and looks like a piston ring seal. This seal must be worn out as opposed to blown out. The compressor showed no signs of leaking. I uploaded some pictures onto my web site at http://kr-2.aviation-mechanics.com/turborepair.htm
I have found a new compressor wheel and a seal and bearing kit at www.htturbo.com they will cost me $89 for the bearings and seals and $51 for the new compressor wheel. My $100. Ebay turbo is now up to $250. That's still not bad. Paul at High Tech Turbo tells me that the trim is 52 and that the turbine housing is a .43 A/R. These numbers are Greek to me.
