BLEW UP AT THE TRACK! Porsche Boxster S M96 Failed Engine Teardown. Don't Do This To Your Porsche!

This week's teardown subject is a Porsche M96.21 6-cylinder boxer engine from a 2001 Boxster S. This engine has 79,500 miles and failed at a track day event. The previous owner said it started making noise and smoking, but was still able to drive itself home! I bought this engine as a core for parts, so lets take it apart to find out what happened, and perhaps why.
Why am I doing this? My name is Eric and I own Importapart. A full service auto dismantler. Part of our model includes dismantling blown up, failed and otherwise bad engines to salvage the good parts. We do not rebuild engines, merely supply parts to those who do!
