Default BLOW up - Survey

Thought it would be interesting to gather some data on engine failures - It would be nice to keep the comments short (no supplier bashing thanks) and just get the facts as you see them for reference.

So how about,

Mileage
turbo
Boost level
octane
Chips
wastegate
boost control
A/f monitoring?
detonation monitoring?
Head gasket type
Intake type
filter
Oil
Damage

Cause ........... The corrugated steel in the headgasket was corroded more than it should after 2.5 years allowing coolant to seep into and fraying the #4 WF ring, eventually weakening the narrowest spot to breakage under high boost.
