THe engine was only out because I was doing a trans conversion (915 to G50). OTher than that nothing was done.... Obviously now that cleaning is a necessity... Coolers, lines, crank, case, yada yada...
I spoke with my contacts at Mobil about this and they haven't seen this type of corrsion with this particular oil, however they going to look at the pictures and run an internal analysis of the oil for me. IN the mean time, it'll be flushed every event. Just more fuel for the waste-oil heater this winter.
