A difficult case for you.
I can say I have never seen a turbo nut come undone under any normal circumstances.
The compressor wheel would show evidence of backfire (wheel blades bent backwards), if it was the cause of the nut coming undone.
My bet is the turbine /compressor wheel assembly wasn't balanced after assembly, and that vibrated the compressor wheel loose.
I would agree that once the claim was accepted, they can't change their mind at that point.
Yes, some turbos are right hand thread, are more to this condition, but generally only after being after being reassembled.
I would say the torque on the nut was not the specified torque by the turbo manufacturer.
That may be hard to prove.
Regardless the insurer said yes to start with, and that would be reason enough for a court case now?

Yes, 30 kms is most certainly abnormal, and most certainly a workmanship/parts failure claim.
I think this is the clincher, a failure at only 30kms.
Ground up alloy can be small enough to go through all of the engine, including the lubrication system.
I feel for your case, I wish I could offer further advice.
Yes, I agree with you.
I fail to see how this can't be honoured by Turbocare.
As far I can can see, a failure has happened within the rebuilt components warranty period.
And on day one, that is just not good enough.
Have you made any mention to them of a pending court case?
I really do feel your pain.
Unfortunately these days, customer service is not what it used to be.
An insurer will look for a loophole.
My bugbear with parts failure claims is they should pay for the full result of the failure, not just the cause.
Good night for now, hopefully tomorrow you will have some more news.
Good luck for the next few days.
Hopefully a good outcome.
Any news on your turbo claim?
As you say James, they gave you a binding contract in agreement.
I would say an independent mechanical asseseor with turbocharger experience should look at it.
To be it is a no-brainer.
Any turbo failure that the engine swallows, should be blamed only on the turbo.
No BOV, aftermarket BOV, different exhaust etc, does not affect the outcome.
If the turbo was spun too hard, ie 25 psi WITHOUT a BOV, then I could see a RH threaded compressor nut coming undone.
But I've never seen this myself.
30 kms, and 2 hits to only 10 psi is workmanship failure, end of story.
Can they not see that?
Even though they did initially agree to the whole claim?
Of course it should include engine rebuild.
