Can you make sense of this Turbo damage?
TL;DR: bearing housing completely shattered
This is what’s left of the turbocharger on my 944 Turbo. How it happened: spirited drive through the mountains, full throttle. Water temps were raised but nowhere near the red mark, oil pressure fine.
Suddenly a huge bang, smoke everywhere and no power. Luckily it didn’t catch fire, as oil also went onto the hot downpipe.
The turbine wheel is mangled, turbine housing cracked and the shaft is bent. Bearings are slightly scratched but not seized or anything. Compressor wheel briefly scratched the housing too.
But most importantly: the bearing housing is completely shattered, so much so that oil and water actually mixed in the turbo and went into the exhaust and oil pan.
Do any experts here have an idea what happened? The seller says he never saw anything quite like it.
