Turbo investigation

[cwspellowe]

Before I go ripping the car to pieces tomorrow, can anyone suggest any reason for this happening?



Compressor housing popped loose as I came back from a test run. It appears the securing washers have bent and allowed it 2-3mm away from the seal.

My thoughts are that.. where I moved the actuator, I used my own bolts and washers to clamp the turbo after clocking it. Is it likely that the washers I used were the wrong size/too weak, and boost pressure overcame them?

Or is something more sinister at work considering oil is leaking out?

Suggestions please...
