No, its not from detonation, that I know for sure as I had the vid running showing the knock sensor not sensing knock when it happend.
Mark, its not from 'worn out' reasons either as no wear is visible. Wear by definition should always be measurable/visible. Not likely either as they run on DLC treated rocker shafts...
But I do also think pure metal fatique could be the most likely cause, probably combined or caused by a does of bad luck from coinciding ignition and/or fuel cut-outs all at once and overboost cut-outs during the tuning I did the days before. These are/can be rather violent.
I have no other explanation as these original rockers are really considered as 'unbreakable' otherwise.

),but they were all on different cylinders.Other than that,I would say that they just wore out and broke,stress cracking and fatigue. But very lucky indeed that it didn´t take a bunch of other parts with it!
