My trophy shelf of blown up parts sure does grow quick! What took me 20 years to accumulate with aircooled failures I'll have far exceeded with the M96 in less than half that time!
I've never seen so much carnage from driving the speed limit!

We finished the autopsy.. The entire bottom end of the engine was garbage..
AWESOME! Now to induct these onto the trophy shelf as offerings to the Gods of speed!

the view..
from an engineering POV it is awesome to see these things scattered about, but as a customer driving the same thing I cringe...
what a condemnation of Porsche business management over quality

With that blackening on the big end, it looks like the rod bearing had been spinning prior to snapping the other bolt.

That happened when just one bolt remained to fasten the rod cap..
The engine still had the factory case half sealant, it had never been torn down.
The bolt wasn't installed loose, the material it is made of and the torque to yield nature of it allowed the bolt to loosen over time and operation.

Maybe Porsche is outsourceing engine assembly or remanufacturing.
Excellent example of why critical bolts don't get installed without final torqueing.
