Or one might could argue that with all that moly they use and type of it , the formlated oil with base stock used " might " not pass one or more of the following tests and whats being seen is a bit of corrosion. And it also might well be that with the different metalurgy used in all these engines some just show different than others .

Recall my bringing attention to the sputter coated bearings used in the VW's and other Bavarian engines .

Cu Corrosion, 3 hrs @ 163C

Zn Corrosion, 3 hrs @ 163C

Pb Corrosion, 3 hrs @ 163C

Al Corrosion, 3 hrs @ 163C

50/50 Pb/Sn Corrosion, 3 hrs @ 163C

That's quite a bunch.
Keep on sharing.
