My guess is maaad prolonged overboost or boost spike. Wastegate must have siezed or something worse. That looks horrible :lol:

you dropped a nut in the cylinder when trying to change your spark plugs and thought it would just come out the exhaust when you started the car up so you put it all back together and went for a drive.

...at that point you figured it would come out quicker if you boosted so you cranked it up and took off... :)


:rolleyes:

gas and det were not factors,no piston damage besides the obvious, no extrordinary knock count.

no busting of nuts, car was untouched for 2 week run, was crusing at 80mph when this happend.
