[928uk] Thrust Bearing Failure

[marton]

Very sorry to hear this.

I think it will be hard to go after the firm because Porsche never 
really admitted the flex plate was the cause of the TBF so where is your 
expert witness?

About cam belt rollers are damaged due to overtensioning of the belt - 
which rollers do you mean exactly?
